But under certain conditions, the inflammatory response produces deleterious effects, resulting in significant tissue damage or even death; this is termed as hypersensitivity […]

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 […]
