Figure 1. TLR2 expression is increased in grey matter of frontal lobes of primates with SIV-induced encephalitis.
In grey matter of control brain, astrocytes (GFAP, red) were generally immunonegative for TLR2 (green). The proportion of astrocytes expressing for TLR2 was significantly increased in animals infected with SIV with encephalitis (SIVE). Scale bar = 25 μm.
