Impaired leptin release

Witryna1 mar 2000 · These findings suggest that the regulation of hypothalamic NPY mRNA by leptin may be impaired with age. To test this hypothesis, we infused saline or leptin for 7 days into ad libitum-fed rats and compared these with saline-infused rats that were pair-fed the amount of food consumed by the leptin-treated rats. We examined daily food … Witryna10 lut 2024 · Thus, if leptin is recognized as one of the adipokines responsible for the low grade inflammation found in obesity, on the other hand, impairments of leptin signaling due to leptin resistance appear to blunt the immunologic effects of leptin and possibly contribute to impaired vaccine-induced immune responses.

Leptin … Witryna26 lis 2024 · Leptin is an adipokine secreted in fat cells [ 6 ]. After leptin is released from the fat cell, it reaches the central nervous system via the blood, binds to its receptor, and reduces food intake through this receptor [ 7, 8 ].
