Figure 1. Elevated expression of TAM receptors in monocytes of older adults.

PBMCs from younger and older adults were labeled for TAM receptors Tyro3, Axl, and Mer and expression was quantified by LSR-II flow cytometry as described [39]. Data shown is percent expression of TAM receptor in CD14⁺, CD11c⁺ monocytes, n = 16 young, N = 21 old, ^* indicates p < 0.02 using multivariate Generalized Linear Models.
