Cytotoxic T cells having heterozygous d-type/k-type class I MHC can lyse infected d-type cells and k-type cells or not. Concept introduction: T cells and B cells are lymphocytes of the immune system which helps to elicit an immune response against an invading pathogen. T cells are antigen-presenting cells (APC). There are three types of T cells: Cytotoxic T cells, Helper T cells and memory T cells. There are other minor types of T cells like natural killer T cell, γδ T cells and many more. The main function of cytotoxic T cells represented as T C have T-cell receptors on the surface of their plasma membrane that has the capacity to recognize specific antigens that can be even nuclear proteins of the pathogen.

Which of the following best describes why it is difficult to develop antiviral drugs? Explain why. A. antiviral drugs are very difficult to develop andhave no side effects B. viruses are difficult to target because they usethe host cell’s enzymes and ribosomes tometabolize and replicate C. viruses are too small to be targeted by drugs D. viral infections usually clear up on their ownwith no problems
