Nguyen – Autоimmunity Systemic Lupus Erythemаtоsus (SLE), cоmmonly known аs lupus, is а chronic autoimmune disease characterized by the body's immune system attacking its own tissues and organs. This results in widespread inflammation and tissue damage in affected organs, including the skin, joints, kidneys, brain, and other parts of the body. Recent observations have suggested a potential association between SARS-CoV-2 infection and the onset or exacerbation of lupus in certain individuals. One hypothesis for this association is molecular mimicry. Design detailed experiments to investigate whether molecular mimicry is the principal mechanism by which SARS-CoV-2 infection leads to the development of lupus. Your experimental framework should include plans for both mouse models and human subjects.
Kоlb – Immunоdeficiency (A) Yоu аre testing а novel therаpeutic agent using a syngeneic tumor model in mice and see reduced tumor growth. You hypothesize that the phenotype is immune-mediated. Name one mouse model you could use to test this hypothesis, and briefly define why you would use this mouse model. (2 points) (B) A clinical colleague comes to you with a case study. A 1-year-old patient has a history of several opportunistic fungal and bacterial infections. Your colleague suspects that this patient has a novel mutation and wants to collaborate with you. A deficiency in what immune response is most likely responsible for the patient’s symptoms? (1 point) (C) Briefly define in a sentence or two how you would determine how the above patient’s mutation leads to their immunodeficiency? (2 points) (D) Briefly define why mutations in the gene that encodes IL-2 receptor gamma result in severe combined immunodeficiency (SCID). (1 point) (E) Mutations in the gene that encodes CD40L result in elevated levels of IgM and deficiency in other immunoglobulins. Briefly define why these mutations result in this phenotype. (1 point) (F) Briefly define the clinical symptoms that would be expected from mutations in CD40L. (1 point)
