Hello students this question asks which type of immunity will immunity will be involved in specific antigen epitope in this diagram you can see that the progenitor cells with epitopes bind to the specific antigen presenting cell as a result cytotoxic t -lymphosides are produced in cellular immune response.
00:36
In cellular immune response, the antigens are recognized by the receptor on that cell.
00:46
As a result of antigen binding to that receptor, there will be production of cytotoxic t -limphosides.
00:55
Therefore, our answer will be option d, that is, cell -mediated, the next question says that t cells, it is a statement says that t cells never bind to free antigens.
01:15
Free antigens.
01:16
It asks whether the statement is true or false.
01:22
The statement is true.
01:26
T cells always bind with the t cell receptors to the antigens presented by the antigen presenting cells.
01:34
So the statement is true.
01:38
The next question says that t cells are activated by antigen bound, antigen bound to cells...
