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...

Mijn cijfer? Een 9! Dit is mijn presentatie van het proefassessment van het thema 'Revalidatie' te Hogeschool Rotterdam, opleiding Fysiotherapie. Mijn uitleg passend bij deze presentatie staat per dia onderaan bij 'notities'. De casus betreft Dhr. Visser van 67 jaar oud en is in het ziekenhuis 2 dagen geleden opgenomen met een cerebellair infarct. Hij is niet meer in staat om zelfstandig te zitten en te staan, er zijn forse coördinatieve problemen van de romp en benen. Dhr. kan zitten m...

1. If person does not meet definition of a patient, release to self. 2. If person does meet definition of a patient and is not A&O, transport. 3. If person does meet definition of a patient and is A&O and suicidal, transport. 4. If person does meet definition of a patient and is A&O, not suicidal, and is under 18 w/o legal guardian, treat under minors protocol (if emancipated can AMA/RMA here; if not, transport under implied consentif unable to reach parent/guardian). 5. If person does mee...

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...

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...

Hoe werkt de cellulaire immuunrespons? Van antigeenpresenterende cellen tot de reactie van T-cellen en B-cellen. Hierbij ook de werking van CD68, CD25, CD40L, CTLA-4, CD80, CD86, verschillende interleukines en de verschillende Th-cellen (Th1, 2, 7 en Tfh).

1) Maturation des cellules dendritiques et différenciation des lymphocytes T CD4+ 2) Réponse de type Th1 : macrophages et lymphocytes cytotoxiques 3) Réponse de type Th2 : macrophages, mastocytes, basophiles et éosinophiles 4) Réponse de type Th17 : réponse locale par les neutrophiles 5) Lymphocytes T régulateurs : inhibition des réponses inflammatoires 6) Réponse humorale : activation des lymphocytes B par les Tfh 7) Les mécanismes effecteurs des anticorps 8) Régulations et ba...
