Homework Answers
Answer:
b) activation of both B cell and the helper T cell
Explanation: B cell act as Antigen presenting cell. When B cell presents the antigen to the Helper T cell, Activation of Helper T cell occurs which is followed by the differentiation fo the T cell into Cytotoxic T cells, Memory T cells, Suppressor T cells, as well as activation and differentiation of B cells into Plasma B cells and memory B cells,

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...
