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...

Janeway’s Immunobiology EXAM- Ch1: Basic Concepts in Immunology WITH well- elaborated questions and 100% correct answers segments encode the last 10-15 amino acids of the variable domain. There are multiple copies of each type of gene segment in the germline DNA, but only one of each type is joined together to form the variable domain. granulocytes - CORRECT ANSWER White blood cells with multilobed nuclei and cytoplasmic granules. They comprise the neutrophils, eosinophils, and basophi...

MCDB 133 W19 Midterm #2 (100 pts) – KEY Grade Stats: 18 people scored 100 or above. Grades are as follows: >/= 90 = A; >/=80 = B; >/=67 = C. >52 = D. Re-grade Policy is same as before, all re-grades need to be to me after lecture by Monday, 4/11. 1. CD4 and CD8 binding are required for TCR signaling. Cells would be initially DP because the cell does not yet know if the newly recombined TCR binds to Class I or Class II MHC, so would need both molecules on cell surface such tha...
