secretion

As expected, the presence of BKCa not only increased lactate secretion, but also increased the ability of breast cancer cells to grow without oxygen.

But we do know infected birds can shed the virus in their saliva, nasal secretions and feces.

They discovered that disruption of the internal clock in the epithelial cells lining the intestine alters secretion of cytokine proteins, leading to heightened inflammation, increased numbers of immunosuppressive myeloid cells and cancer progression.

They found that UV radiation inhibits weight gain by enhancing secretion of the neurotransmitter norepinephrine, which not only decreases leptin but also increases energy expenditure through the "browning" of subcutaneous fat.

More recent laboratory tests have also detected the virus in cows' nasal secretions for a short time before the virus presents in their raw milk.
