Answer: there can be two possibilities and both may work hand in hand- B.The patient's own immune system would destroy the transfused T cells before they could respond to the viral infection and
D.Donor T cell viral antigen recognition is restricted by MHC molecules not expressed in the patient.
Explanation: MHC class II are expressed on B and T cells and they will be responsible for presenting the viral peptide to T cells who will then recognize and initiate the reactions to remove viral cells.An effective immune response against viral infections depends on the activation of cytotoxic T cells that can clear infection by killing virus-infected cells. Proper activation of these T cells depends on professional antigen-presenting cells, such as dendritic cells (DCs)
Perforin first makes a pore, or hole, in the membrane of the infected cell. Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside. This is why Killer T-cells are also called Cytotoxic T-cells. The pieces of destroyed cells and viruses are then cleaned up by macrophages.
