When they delivered UV radiation to mice whose keratinocytes lacked p53, POMC production was not induced and the mice did not tan. The implications of the research go beyond tanning.

White blood cells in lung produce histamine seen in allergies

... though there were no mast cells, histamine levels rose up to 50 times normal." The reason was straightforward, Caughey says. Neutrophil numbers increased in response to infection, and neutrophils in turn produced histamine. "It's a direct effect of the mycoplasma bacteria on neutrophils. They induce ne...
