Helper T cell

...s , proteins or peptides that stimulate other lymphocytes ; the most common is interleukin-2 (IL-2), which is a potent T cell growth factor. Activated, proliferating T H cells can differentiate into two major subtypes of cells, Th1 and Th2 cells. These subtypes are defined on the basis of specific cyt...

Cloning

...se, therefore, is a single cell (like bacteria , lymphocytes etc.) or multi-cellular organism that is genetically identical to another living organism. Sometimes this can refer to "natural" clones made either when an organism reproduces asexually or when two genetically identical individuals are produce...

Cartilage

...tilage acts as a barrier, preventing the entry of lymphocytes or diffusion of immunoglobins . This property allows for the transplantation of cartilage from one individual to another without fear of tissue rejection. Bioengineering techniques are being developed to generate new cartilage, using a cellula...

B cell

B cells are lymphocytes that play a large role in the humoral immune response (as opposed to the cell-mediated immune response ).The abbreviation "B" stands for the bursa of Fabricius which is an organ unique to birds, where B cells mature. It does not (as commonly...
