Complement mRNA is differentially upregulated by immune and neuronal cells in the infected brain
(a) In situ hybridization (ISH) for C1qa and IHC for IBA1 in layer V of neocortex of mock- and Toxoplasma gondii (ME49)-infected mice.
(b) ISH for C3 and IHC for IBA1 in layer V of neocortex of mock- and ME49-infected mice.
(c) ISH for Syt1 and C1qa showed no neuronal expression of C1qa mRNA in both mock- and ME49-infected layer V.
(d) ISH for Syt1 and C3 in mock- and ME49-infected mice. Neuronal expression of C3 mRNA was detected in some neurons in ME49-infection.
(e) ISH for Npnt and C3 in mock- and ME49-infected mice. C3 mRNA was detected in some Npnt-expressing pyramidal neurons in layer V of neocortex.
(f) ISH for Gad1 and C3 show no expression of C3 mRNA by inhibitory neurons in ME49-infection.
