Immunology Exam 3 - Questions and Answers Patients with the disease X-linked lymphoproliferative syndrome (XLP) lack expression of the small adapter protein SAP, which associates with receptors of the SLAM family. One characteristic of this disease is an inability of cytotoxic T cells to control infections with a virus, Epstein-Barr virus (EBV), that replicates in B cells. This defect in control of EBV results from: A. A defect in antibody responses to EBV due to impaired T cell help for B cell...

BOARD REVIEW IMMUNOLOGY + LECTURIO Question and answers already passed 2023/2024 Lymph node structure: - correct answer 1) *Germinal Center:* Where mature B cells proliferate, differentiate, and mutate their antibody genes (through somatic hypermutation aimed at achieving higher affinity), and switch the class of their antibodies (for example from IgM to IgG) during a normal immune response to an infection. These develop dynamically after the activation of follicular B cells by T-dependent...
