Objective: To evaluate for racial differences in triggering receptor expressed on myeloid cells 2 (TREM2), a key immune mediator in Alzheimer disease, the levels of CSF soluble TREM2 (sTREM2), and the frequency of associated genetic variants were compared in groups of individuals who self-reported their race as African American (AA) or non-Hispanic White (NHW).
Methods: Community-dwelling older research participants underwent measurement of CSF sTREM2 concentrations and genetic analyses.
Results: The primary cohort included 91 AAs and 868 NHWs. Read More
