- This term describes an antigen that is too small to be immunogenic, however it binds to proteins in the body to increase its size, allowing it to then be able to trigger an immune reaction: O 1) hapten O 2) alloantigen 3) superantigen O 4) epitopearrow_forward“T-lymphocytes are the most important arm of the immune response in protecting the community against virus infection.” Do you agree with this statement? Explain your reasoning in detailarrow_forwardYou encounter a patient who can't seem to fight off infections that normal patients can. You suspect that there must be something wrong with the T-Cells. You isolate the cells from the blood, and see that they have normal functioning T-Cells. The CD8T- cells can secrete granzymes when activated, and the CD4 T-Cells can secrete cytokines when activated. You then decide to draw blood of the patient, and see that there is a low level of cytokines present during the infection. Give 2 explanations of what you think is wrong with this patient?
