Question

 

• Could the adaptive immune system operate without the innate immune system? Give at least 2 examples to support your answer.
• If you had to choose between losing function of your B or T cells, which would you choose and why?

Answer 1

Ans. Adaptive immune defences consist of antibiodies and lymphocytes,called humoral response and the cell mediated response . The term adaptive refers to the differentiation of self from non- self ,and the tailoring of the response to the particular foreign invader. The ability to shape the response in a virus- specific manner depends upon communication between the innate and adaptive system . This communication is carried out by cytokines that bind to cells, and by cell-cell interaction between dendritic cell and lymphocytes in lymph node. This interaction is so crucial that adaptive response cannot occur without an innate immune system

.eg. detection of Pramod by PRR leads to the induction of inflammatory response and innate host defence . In addition ,the sensing of microbes by PRRs expressed on antigen- presenting cells ,dendritic cell leads to active of adaptive immune response .

Actually ,B cell are as important as T cell and are much more than just a final clean-up crew. They make important molecule called antibodies . These molecules trap spacific invading virus and bacteria . Without this line of defence ,our body would not be able to finish fighting most infection.T cell also determine the specificity of immune response to antigen in body so,both cells are important we can't choose any of one.
