Question 1

hypersensitivity?

Answer 1

inflammation, consisting of leukocyte recruitment and activation, accompanies many of the reactions of CD4 + T lymphocytes. This T cell–dependent inflammation serves as an antimicrobial defense mechanism but also can be injurious to tissues. When a T cell reaction causes injury, it is called delayed-type hypersensitivity (DTH) , the term hypersensitivity referring to an excessive or damaging immune response.
