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.

Answer:
Care networking is defined as when a patient is being scared not from person but from the team of doctors are expert. This is more advantageous than being treated as solo.
Explanation:
The care networking advantages that a group of experts is given a job to take care of the person and it is very efficient when compared to a solo. Rather than expert all the non-expert like friends’ neighbors and relatives of the patient are also involved while giving the treatment. The patient is monitored all the time by the expert.
Care networking also gives the patient a chance to speak about the condition to their expert or friends when they feel alone or sad. By this method can reduce the mental stress and it is very beneficial for the patient for the recovery.
