CX3CR1 and Alzheimer disease: To investigate a possible effect of gal3 on some of the gal3-activation/responses-associated genes related to microglial AD phenotype, we assessed the expression of Trem2, Tlr4, Clec7a, and Cx3cr1 transcripts in some of the recorded slices (30 min after gamma oscillation induction, see Fig. 4a).
