Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.

Serotonin is a neurotransmitter that is a small, soluble molecule. P11 (a small protein) is required for transport of serotonin receptors to the cell surface. Assume for this problem that p11 affects transport of serotonin receptors only, and that it does not affect transport of any other proteins (a simplification). Depressed people seem to have low levels of p11; treatments that improve mood increase the expression of the p11 gene. NSAIDs (aspirin, ibuprofen, etc.) seem to decrease expression of p11. SSRIs (selective serotonin reuptake inhibitors) decrease re-uptake of serotonin at synapses. Some depressed patients are helped by SSRIs, but some are not. Explain both parts of B. B-1. The results indicate that depression can be caused by levels of serotonin receptors that are (higher than normal) (lower than normal) (neither – no evidence here for any effect on depression) (higher or lower but can't tell which).

You are given a project to characterize the effect of mutation on two newly discovered G protein coupled-receptors, GPCR-UCI and GPCR-UC2, both of which bind to the same ligand. For the cell signalling assay, you have the UMR-106 cell line that expresses both GPCR-UC1, CPCR- UC2, the corresponding G proteins, and adenyl-cyclase. A basal adenylyl cyclase activity, and thus, a baseline cAMP concentration, is detected in the cell line. (i) You found that, upon binding to the ligand, the mutation in GPCR-UC1 results in increased CAMP level but the mutation in GPCR-UC2 results in a low cAMP concentration. Based on these results, identify the subclass of G protein isoforms that the GPCRs activate. Explain your answer. (ii) If the mutation affects the G protein from GDP release, how would this affect the CAMP production after ligand binding? Explain your answer.
