During
an immune response, dendrite cell activates Helper TH
cells. Antigen-MHC binds to the TCR complex and CD4. Activates
Helper TH cells. Activated Helper TH cells
stimulate the dendritic cells, And it activates CD 4+ T
cells. Dendritic cells with CD 4+ T molecule activates
Cytotoxic T cell.

Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...

answer all the questions answering one question is not helpful 1. A helper T cell is capable of helping another cell because it expresses a protein on its surface that binds to a different protein on the surface of the cell being helped. What are these proteins (on the T cell, and on the cell being helped)? CD28, and B7 TNF, and TNFR Class I MHC, and TCR CD40L, and CD40 CTLA-4, and B7 2. Helper T cells are restricted...
