What Causes Hyponatremia?
Discussion Normal kidneys regulate water balance to maintain a plasma osmolality of 275-290 mOsm/kg normally. Thirst and arginine vasopressin or antidiuretic hormone (ADH) are the primary regulators of plasma osmolality. ADH is made in the hypothalamus and released by the posterior pituitary gland. ADH acts on the kidney’s distal collecting duct to increase water reabsorption. ADH is appropriately released in hypovolemic states, such as dehydration caused by gastroenteritis. ADH has an ~10 minute half-life and therefore can respond to rapid changes in volume status. Sodium balance is regulated by aldosterone (as part...

How highly contagious norovirus infection gets its start
(Washington University School of Medicine) Researchers have shown, in mice, that norovirus infects a rare type of intestinal cell called a tuft cell. Noroviruses tucked inside tuft cells are effectively hidden from the immune system, which could explain why some people continue to shed virus long after they are no longer sick. These 'healthy carriers' are thought to be the source of norovirus outbreaks, so understanding how the virus evades detection in such people could lead to better ways to prevent outbreaks.

Tropism for tuft cells determines immune promotion of norovirus pathogenesis
In this study, we have shown that tuft cells, a rare type of intestinal epithelial cell, express CD300lf and are the target cell for MNoV in the mouse intestine. We found that type 2 cytokines, which induce tuft cell proliferation, promote MNoV infection in vivo. These cytokines can replace the effect of commensal microbiota in promoting virus infection. Our work thus provides insight into how the immune system and microbes can coordinately promote enteric viral infection. (Source: ScienceNOW)
