Herpes Simplex virus, causes recurrent cold sores in infected individuals. Which of the following explains the recurrent infections?

Pathogens are taken up using the following mechanisms EXCEPT:

Attachment of HIV is possibe by the interaction of the…………………….with CD4

In the absence of disease, large numbers of effector TH17 cells are abundant in the intestinal lamina propria. In a healthy individual, these TH17 cells

In addition to Peyer’s patches that resemble systemic lymph nodes, the intestinal epithelium also contains several thousand isolated lymphoid follicles. Unlike the organized secondary lymphoid tissues in the mucosal immune system, these lymphoid follicles:

Provirus stage in HIV infection is the latency stage

X-linked agammaglobulinemia (BTK tyrosine kinase deficiency) is due to

B cell activation and differentiation ensues after HIV entry into host

Effector cells of the MALT are found in the following locations:

Mice lacking the poly Ig receptor  have an immunodeficiency disease characterized by increased susceptibility to mucosal infections. Yet, a genetic deficiency in the production of IgA antibodies is the most common form of human immunodeficiency, and is generally a mild disease and often even asymptomatic. This dichotomy can be explained by:
