PTPRC and Alzheimer disease: The results showed that the expression levels of GRB2, HSP90AA1, HSPA4, IGF1, KARS, PIK3R1, and PTPN11 were significantly decreased in the AD group compared with the HC group (Figures 3G–J,L–N), and the expression levels of CD86, FOS, JUN, PTPRC, STAT3, and TLR2 were not statistically different between the AD and HC groups (Figures 3E,F,K,O–Q).
