They may be found as membrane receptors in the endosomal membrane of cells c. They may be found as soluble receptors in the cytosol of cells d. They can react to every possible structural detail of microorganisms. e. a and b 4. Which of the following is an example of intrinsic immunity? a. natural killer cells b. anti-microbial peptides in skin c antibodies d. plasma cells e. CD8 T cells

Explanation / Answer

3. The answer is

b. TLR may be found as membrane receptors in the endosomal membrane of the cells.

Explaination:

TLRs are membrane receptors which found on endosomal membranes of macrophages, dendritic cells in humans. In human 10 TLRs are present.
