Tenascin-C (TnC) changes M1/M2 phenotype in psychosine-treated microglia/globoid
cells. (A, B) Isolated microglial cultures were grown on either laminin (Lm)
(A) or TnC (B) and treated with psychosine for 7 days.
Expression of M1 and M2 markers (major histocompatibility complex II [MHCII], CD206,
respectively) was identified by immunocytochemistry. Representative images show that with
microglia plated on Lm predominantly express CD206 but not MHC II (A), while
cells grown on TnC predominantly express MHC II, but not CD206 (B). (C,
D) Data represent percent of marker-positive cell staining of total cell
number/field (n = 5–8 fields per treatment) (mean ± SE), **, p <
0.01. Scale bar: 20 µm.
