I)What T cell subset would be stimulated by a virus? Why?

J)What are cell adhesion molecules (CAMS) and how are they used by leukocytes? Give an example of a cell adhesion molecule.

Solution

J) CAMS are the protein found on the cell membrane of the cell which helps them to bind them to the other cells present near to them present in the extracellular matrix..!! The example of cell adhesion molecules are integrin, cadherins, selectins..

The use of CAMS in leukocytes is the it helps in extravasation of the leukocytes from the circulatory system to the tissue whre the tissue damage or infection had occurred which is the first line of defense in the body among the pathogens..!! The movement occurs by the process of diapdesis..!! The example of CAMS used hre is integrin..

I) The T-Cells affected by the viruses are mostly the T-helper Cells which has Cd-4+ receptors present on them.. When the virus enter into the body it is the T-helper cells which recognize the virus or the antigen and gives signals to the other immune cells of the body.. Hence those cells are affected first to lower down the immune system of the body
