HEK293T cells transfected with TREM2 or AD variant incubated with 500 nM Aβ42 monomers were lysed for Aβ42 quantifications by ELISA. Expression of TREM2 increases Aβ42 level detected compared to mock control as well the AD variant. Results were averaged ± standard error (n = 9, # p < 0.05 compared with TREM2, ## p< 0.01 compared with TREM2, *** p< 0.001 compared with mock, **** p <0.0001 compared with mock, ANOVA, Tukey's Multiple Comparison Test, see Appendix table S3 for p value)
