  • Ira Mellman (Genentech) Part 2 Antigen Presentation and Dendritic Cells The immune response integrates two distinct systems of innate and adaptive immunity discovered over 100 years ago. Linking these two arms of the immune response is the task of a comparatively recently identified cell type, the dendritic cell. Dendritic cells have the capacity to detect the conserved microbial products that activate cells of the innate immune response and capture the dramatically wider diversity of microbial antigens to prime antibody and T cell responses characteristic of adaptive immunity. The unique capacity of dendritic cells for antigen processing and presentation reflects a series of remarkable specializations of basic principles of cell biology. See more at
  • Immune System Strike Against Lung Cancer Th17 Cells Summon an Immune System Strike Against Cancer Helper T cell's effect raises possibility of cellular therapy, vaccine development T cells are lymphocytes, a type of white blood cell produced by the thymus equipped with receptors that recognize and bind to antigens, pieces of invading organisms presented to the T cells by dendritic cells. The bound antigen converts the T cell to T helper cells that secrete signaling molecules called cytokines to launch an appropriate immune response. Helper cells, in effect, guide the adaptive immune response. In the Immunity paper, additional experiments outlined the specific pathway by which Th17 suppresses tumors: Tumor invasion of the lung attracts Th17 cells that secrete IL-17A. IL-17A in turn promotes the secretion of two chemokines, CCL2 and CCL20, which recruit leukocytes to the tumor site. The leukocytes include dendritic cells, which seize tumor antigens and migrate to the lymph nodes. There, the antigens are used to prime CD8+ killer cells, which then migrate to the lung and kill established tumors.
  • Immunoglobulin Gamma- Jeff Cuaron This short video clip displays the light and heavy chain of a single domain of Immunoglobulin Gamma in a 3-D view. Immunoglobulin is constructed of 2 heavy and 2 light chains that are bound by disulfide bridges. The antigen binding site is located in the gap between the ends of the red and yellow chains. The antigen binding site is where the antibody binds specifically to one or more recognized antigens by their determinants. The video shows, at the pause, that the structure of the bound domain of light and heavy chain allows for an antigen to attach itself between the red and yellow areas at the end of the molecule due to the absence of bulky bonds between the two chains. On immunoglobulin, there is 2 antigen binding sites for every molecule and specifically Immunoglobulin Gamma displays a 'Y' molecular shape when not bound to an antigen.

English: when the skin as the barrier is injured bacteria can enter. Macrophages migrate from the blood vessels into the tissue. and start their job as big eater. Beside unripe dendritic cells which are existing in the tissue are also eating some of the invaders and go to the lymphnodes to do their job: they fragment the bacteria and bind harmless parts of it to the MHC. These complexes, the so called antigens are presented on the cell surface. All white blood cells are flushed in periodic intervals through the lymphnodes. The T cells are binding accidential. If the MHC with the antigen fits to the T cells receptor like lock and key the T cell is activated and starts to divide. Meanwhile the macrophages are sending second messengers that helps the Th cellsand B cells to find the damage spot.. The b cells can ingest invaders and present the antigen. the activated Th cells are attracted and bind to the complexes. That stimulates the b-cell to divide and produce antibodys which bind to the bacteria and initiate their ellimination
  • Antibodies "Antibodies of the immunoglobulin G class are Y-shaped glycoproteins that circulate in the bloodstream. They bind to and inactivate foreign molecules—the antigens—and mark them for destruction. Each IgG molecule consists of two light chains and two heavy chains. The heavy chains have carbohydrates attached. The regions of the antibody that bind to antigens are located at the very tips of the two arms. Each arm of the antibody is composed of four domains. Two are called the variable domains, contributed by the heavy and light chains, and hence called VH and VL. The variable domains are attached to two constant domains, again one each from the heavy and light chains, and hence called CH and CL. Variable and constant domains share a similar structure, called the Ig fold. Each domain consists of a pair of beta sheets, one with three strands and one with five. A single covalent disulfide bridge holds the two sheets together, which results in a rigid and very stable domain. As their name implies, the variable domains vary in amino acid sequence from one antibody molecule to another, thus providing the vast diversity in structure required by the immune system. The antigen-binding site in the variable domains is composed of hypervariable loops that are especially susceptible to sequence variations. Sequence variations in the hypervariable loops are responsible for the specificity of antibodies to particular antigens. Antigens bind to the tip of each antibody arm, generally two ...

  • Rhesus Negative Blood Type If the RH-negative factor is a 'normal' presentation of blood, then why is there a problem when a mother of the RH-negative blood group gives birth to an RH-positive blood group baby. This Hemolytic disease, actually an allergic reaction, can cause death when the two different blood groups are mingled during pregnancy. When the antigenic substances attack the negative blood group it can destroy the blood cells. So why does the human body produce antigens to this blood type? Where did the Rh negatives come from? Why does the body of an Rh negative mother carrying an Rh positive child reject her own offspring?
  • HIV NEW TREATMENT LATEST RESULTS & P24 ANTIGEN TEST NEG As i have been in Australia for some time now I decided to get retested here to see what came up. Not surprisingly my result came back positive as expected. I will have antibodies in my body for many years just like i have for chicken pox or any other virus i have picked up over the years. The p24 Antigen test came back negative however and while this is good news testing for p24 antigens is very difficult as they are very hard to detect after initial infection.. I think this is why hiv is such a difficult thing to say conclusively that a person has been cured or not as the nonsense created around it is pure bull***.

  • Competitive ELISA ( ) - In competitive ELISA, unlabeled antibody is incubated in the presence of its antigen. Then these bound antibody complexes are then added to an antigen coated well. After washing, unbound antibodies are removed. The more ***ytes in the sample, the less antibodies will be able to bind to antigens in the well. The signal is then detected using labeled secondary antibodies and the decrease in signal is compared to a control. The major advantage of a competitive ELISA is the ability to use crude or impure samples and still selectively bind any antigen that may be present. More videos at Abnova

Why Rare Blood Types Arranging rare blood types donor ( rh negative rare blood types ) is always a tough task as awareness on rare blood types is still low and usually getting started on the search for rare blood types draws a blank with most people. part from providing blood donors of rare blood types to sick patients, Rare Blood ( official website for Rare Blood Types ) is also working hard to create awareness about voluntary blood donation of rare blood types in India. Rare Blood Types or Regular Blood Types every one should donate blood regularly. Your blood type depends on the presence or absence of specific substances on the surface of red blood cells. Red blood cells are the portion of blood responsible for carrying oxygen throughout the body. These substances, called antigens, are made of mostly protein and carbohydrates and differ from person to person. Blood groups—the most familiar being A, B and O—are descriptions of certain antigens found on red cells. People with type A blood have A antigens on their red blood cells and lack B antigens; people with type B blood have B antigens and lack A antigens; people with type AB blood have both antigens, and people with type O blood lack both A and B antigens but have others. However, there are more than 600 known antigens besides A and B that characterize the proteins found on a person's red cells. A combination of some of these less ...
  • Blood groups and Blood compatibility Check us out at A total of 30 human blood group systems are now recognized by the International Society of Blood Transfusion (ISBT).[2] A complete blood type would describe a full set of 30 substances on the surface of RBCs, and an individual's blood type is one of the many possible combinations of blood-group antigens. Across the 30 blood groups, over 600 different blood-group antigens have been found, but many of these are very rare or are mainly found in certain ethnic groups. Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease. An example of this rare phenomenon is the case of Demi-Lee Brennan, an Australian citizen, whose blood group changed after a liver transplant.[9][10] Another more common cause in blood-type change is a bone marrow transplant. Bone-marrow transplants are performed for many leukemias and lymphomas, among other diseases. If a person receives bone marrow from someone who is a different ABO type (eg, a type A patient receives a type O bone marrow), the patient's blood type will eventually convert to the donor's type. Some blood types are associated with inheritance of other diseases; for example, the Kell antigen is sometimes associated with McLeod syndrome.Certain blood types may affect susceptibility to infections, an example being the resistance to specific malaria species ...

  • cellular immune response.MOV Cell-mediated immunity is an immune response that does not involve antibodies or complement but rather involves the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. Historically, the immune system was separated into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells. CD4 cells or helper T cells provide protection against different pathogens. Please note that T cells cause death by apoptosis without using cytokines, therefore in cell mediated immunity cytokines are not always present. Cellular immunity protects the body by: 1. activating antigen-specific cytotoxic T-lymphocytes that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens; 2. activating macrophages and natural killer cells, enabling them to destroy intracellular pathogens; and 3. stimulating cells to secrete a variety of cytokines that influence the function of other cells involved in adaptive immune responses and innate immune responses. Cell-mediated immunity is directed primarily at microbes that survive in phagocytes and microbes that infect non-phagocytic ...
  • Osborne - Immunice Video Testimonial Inside your body is a protection mechanism called the Immune System. It is designed to defend you against millions of bacterias, microbes, viruses, toxins, and parasites trying to invade your body to make you sick. Your Immune System responds and eliminates the invaders while the skin heals itself and seals the puncture. In rare cases, the Immune System misses something and the cut gets infected. It gets inflamed and will often fill with pus. Inflammation and pus are both side-effects of the Immune System doing its job. A red, itchy bump from a mosquito bite is a visible sign of your Immune System at work. Germs trying to get in your body through food intake die in the saliva or the acid of the stomach. But when one germ gets through and causes food poisoning, the most common responses from your Immune System are vomiting and diarrhea. These are but few examples of how you are preserved by your Immune System and that to take it for granted great brings in risk of body system failure and decreased longevity. The Immune System protects you from infection with layered defenses of increasing specificity. Physical barriers provide an immediate, but non-specific response by prevent pathogens (any organism capable of producing disease such as bacterias and viruses) from entering the body. These barriers include the skin, the mucuos membranes covering your eyes, alimentary c***, and genito-urinary tract. The langerhan cells in the skin are involved in ...

  • Antigen: protease degradation - PMAP Antigen processing is a biological process that prepares antigens for presentation to special cells of the immune system called T lymphocytes. This process involves two distinct pathways for processing of antigens from an organism's own (self) proteins or intracellular pathogens (eg viruses), or from phagocytosed pathogens (eg bacteria); subsequent presentation of these antigens on class I or class II MHC molecules is dependent on which pathway is used. Both MHC class I and II are required to bind antigen before they are stably expressed on a cell surface. The endogenous pathway is used to present cellular peptide fragments on the cell surface on MHC class I molecules. If a virus had infected the cell, viral peptides would also be presented, allowing the immune system to recognize and kill the infected cell. Worn out proteins within the cell become ubiquitinated, marking them for proteasome degradation. The exogenous pathway is utilized by professional antigen presenting cells to present peptides derived from proteins that the cell has endocytosed. The peptides are presented on MHC class II molecules. Proteins are endocytosed and degraded by acid-dependent proteases in endosomes; this process takes about an hour.

  • MHC Class 1 "Class I major histocompatibility complex proteins display short peptides, or antigens, derived from normal cell proteins. Peptide-loaded MHC proteins are located on the cell surface where they can be examined by passing T cells of the immune system. The MHC complex has two subunits. The smaller subunit, b2 microglobulin, resembles an immunoglobulin domain. The larger a subunit also has an immunoglobulin-like domain which is linked to a head domain containing the antigen-binding groove. The antigen-binding groove in the MHC head domain is built from two walls composed of long alpha helices that rest on a floor composed of an eight stranded beta sheet. The peptide on display fits snugly between the helices in the groove.The peptide backbone is bound at both ends by highly conserved regions of the MHC protein. Some peptide side chains extend downwards into specific binding pockets in the groove, while other peptide side chains project upwards where they can be recognized by T cells. MHC class I proteins display their bound peptides on the cell surface for immune surveillance. Immune cells, called cytotoxic or killer T cells, for example, express T-cell receptors that bind to the MHC head domain and the bound peptide. If the cell expressing the MHC protein displays a peptide foreign to the immune system, the T cell is activated by this receptor-MHC interaction. The activated T cell then proceeds to destroy the abnormal cell. Cut-away views of this peptide-bound MHC protein ...
