Fig. 6. eNampt-EVs purified from young mice boost NAD+ in the hypothalamus, particularly in the ARC and DMH, but not the liver.
a NAD+ levels in liver samples of 22-month-old mice 30 min after administration of eNampt-EVs or PBS (n = 5). b NAD+ levels in the whole hypothalami of 22-month-old mice 30 min after administration of eNampt-EVs or PBS (n = 8). c NAD+ levels in the ARC, VMH, DMH, and LH of 22-month-old mice 30 min after administration of eNampt-EVs or PBS (n = 5). *p ≤ 0.05 by unpaired Student’s t-test. Error bars indicate s.e.m.
