(15-pоints) Recently, knоwledge аbоut the kinds of cells in а humаn and what they do has been turned on its head by a new international scientific consortium, The Human Cell Atlas. New techniques in anatomical isolation and sequencing (e.g., single cell drop-seq) have, for example, defined 39 previously unknown functional cell types in the retina and 6 new dendritic cell families in the blood. One of the leaders of this consortium, Prof. Aviv Regev of the Broad Institute (MIT & Harvard) and VP of R&D at Genentech, has said that despite all this complexity, the control of human physiology can be distilled into three sets of sensing/control systems: “the immune system, the nervous system, and fibroblasts”. Thinking about Cannon’s Postulates of Homeostasis, and the systems discussed in BIO 553, do you think Prof. Regev’s assertion is adequate or not? You need to defend your answer with specific examples, demonstrate you know and can apply Cannon’s Postulates, and you must address two of her assertions – nervous and immune systems – don’t worry about fibroblasts because we never talked about them.
(2-pоints) Stаrvаtiоn, аnоrexia, and repeated strenuous exercise (for example, ultra-endurance sport) can all induce amenorrhea – lack of menstruation in a female during her reproductive years. A) Propose a signal responsible for this? B) Paradoxically, related to the same signal, obesity also induces amenorrhea, explain this given your answer to part A.
