Adaptive immunity 2025-26

1. This type of immunity is temporary since immune system is not activated to produce effector molecules
4. Because of this phenomenon adaptive immune system acts more faster when it encounters same pathogen second time and subsequent times
6. T lymphocytes recognise processed microbial antigens when they are presented along with ..... molecules
8. Exposure to..... will give rise to natural active immunity
11. These are products of plasma cell play a key role in defense agains extracellular bacteria
12. CD8+ cells are important for defense against ............. pathogens
13. These are enzymes present in lysosomes that assist in degredation of bacterial proteins within the endocytic vesiscle or phagolysosome
15. This is one of the mechanisms by which virus particles or bacterial toxins present outside the cell are eliminated by antibodies
17. These cells mediate adaptive immune responses
18. These toxic substances produced by activated CD8+ cells cause apoptosis of the infected cells
19. The CD8+ cells are also called as ..... cells
20. Antibody-mediated immunity is also called as ........ immunity

1. These proteolytic enzymes present in the cytoplasm degreade microbial proteins into smaller peptides
2. This is an example for primary lymphoid organ
3. This procedure will give rise to artificial active immunity
5. This cell engulf large amount extracellular fluid that may contain microbes
7. The proliferation of lymphocytes specific to an antigen is referred to as ……..
9. These cytoplasmic proteins play a key role in transporting microbial peptides from cytoplasm to endoplasmic reticulum
10. These cells are terminally differentiated B lymphocytes that produce antibodies
11. This cytokine plays a key role in differentiation of naive T helper cell into T helper 1 cell
14. This type of T cells have CD4 surface markers and mediate functioning of many cells such as macrophages, B lymphocytes and others
16. ……… type of antibody is passively transferred from mother to babies through placenta
