Fig. 1.

TCRβ mRNA is expressed in the mouse brain. Cryostat sections from postnatal days 0, 4, 7, 28, or 40 were either stained with cresyl violet or hybridized with a probe for TCRβ C regions. (A) Coronal sections. (B) P40 TCRβ^-/- and TCRβ wild-type sense control sections are similar to the P40 section hybridized with TCRβ antisense probe. (C) Sagittal sections, anterior to the left. TH, thalamus; AG, amygdala; dLGN, dorsal lateral geniculate nucleus; vLGN, ventral lateral geniculate nucleus; CTX, cortex. (Scale bars, 1 mm.)
