Quick Notes on Hypersensitivity (With Diagram)

Immune response recruits and mobilizes a series of effector molecules that induce a localized inflammatory response, which ultimately removes the antigen. This inflammatory response usually does not extensively damage the host tissues. But under certain conditions, the inflammatory response produces deleterious effects, resulting in significant tissue damage or even death; this is termed as hypersensitivity or allergy. Hypersensitive reactions may [...]

Cell-Mediated (Cellular) Immunity: Notes | Immune Responses

The below mentioned article provides notes on cell-mediated (cellular) immunity. The cell-mediated or cellular immunity is that where the T-lymphocytes destroy other cells having antigens on their surface without any mediation by antibodies. The precursors of T-lymphocytes produced by stem cells of bone marrow pass through liver and spleen before reaching the thymus where they are processed, hence called thymus-dependent [...]

Primary and Secondary Immune Responses

The B and T-lymphocytes that are yet to encounter an antigen are called naive B and naive T-cells. The naive B-cells that encounter the antigen, proliferate and differentiate into two types of cells: the antibody-secreting plasma cells and the memory B-cells. The plasma cells form the basis of primary immune response, which is the response mounted by the immune system [...]
