Fig. 1From: Proteomic analysis of aged microglia: shifts in transcription, bioenergetics, and nutrient responseAge-related differential expression of selected microglial proteins. SILAC or label-free ratios were determined by MaxQuant and then normalized to the young group for each individual protein. Error bars represent SEM and statistical significance was determined by Welch’s t test (p < 0.05) and |z-score| >1Back to article page
