Note that most of the “chemical” components are antimicrobial peptides We often think of “immunity” to only be about T-cells, B-cells and cytokines. But the first line of defence against pathogens is something much simpler, which also stops most of threats. This first line of defence are the anatomical barriers of your body. Every body sur...")

Communication between cellular components of the immune system (Created page with "Many different types of molecules facilitate communication between cells. == Adhesion molecules == Adhesion molecules make it possible for two cells to communicate directly. Like a form of “handshake”, two cells each contain molecules that bind to each other and induce changes inside the cell. This interaction does not always depend on antigens. There are five families of adhesion molecules. === Ig-superfamily === The first family is the Ig-superfamily. It contains...") Tag: Visual edit

Recognition molecules, MHC molecules (Created page with "While B-cells can bind free antigens in the blood and tissues, T-cell receptors can only bind to antigens that are being presented to them by other cells. This means that a T-cell cannot recognize a bacterium or virus floating past; some other cell has to digest the bacterium or virus and then ''present'' a small part of it, an antigen, from the pathogen to the T-cell for it to be activated. == Major histocompatibility complex == A protein called major histocompatibilit...")

Molecular components of the immune systems (Created page with "== Antibodies == An antibody or immunoglobulin is a molecule found in the body that binds to antigens on pathogens. It does this to make it easier for the body and immune cells to get rid of the pathogens. The specific ways the immunoglobulin do this is written in more detail in topic 13. The antibodies are the main component of the humoral (non-cellular) immune response, a part of the adaptive immune response. Antibodies are basically receptors; they are proteins that...")

Introduction to immunology (Created page with "== Antigen == An antigen is any molecule that can be recognized by special receptors on the T and B-cells or antibodies, and they induce either an immune response or immune tolerance. The last part is important, because an antigen isn’t just something foreign that triggers an immune attack. We mostly think of antigens as something that’s only found on pathogens like bacteria or viruses. However, every protein in your body is an antigen, but none of the proteins in yo...")

It is a quantitative method, which means that it can be used to accurately determine the concentrations of the investigated molecule. It works similarly to immunohistochemistry, in that we use antibodies that are bound to an enzyme. This antibody binds to the antigen we want to investigate, and the enzyme will catalyse the conversion of a non-colorful chromogen to a colourful molecule. The light absorption can be measur...")

This technique is called flow cytometry because it lets cells flow through a very small tube and uses this to analyse their properties. Let’s say we’d like to analyse the size of a bunch of cells in a Petri dish. We put these cells into a flow cytometer, which will direct the cells into...") Tag: Visual edit

Both slides are of a breast cancer. The upper cancer is positive for an antigen called HER2, while the lower cancer is negative for the same antigen. The treatments will therefore be different.
