Abstract

CD4+ T cells rescue facial motoneurons (FMN) from axotomy-induced cell death. The objective of this study is to determine if the CD4+ T regulatory subsets, CD4+CD25+ T or CD1d-restricted NKT cells are critical for FMN survival after facial nerve axotomy. Surviving FMN within facial motor nuclei from axotomized and control sides 4 weeks after axotomy were counted to determine percent FMN survival. Data generated by applying this paradigm to recombination activating gene-2-deficient mice reconstituted with CD4+ T cells depleted of CD4+CD25+ T cells and to CD1-/- mice, deficient in CD1d-restricted NKT cells, suggest that neither regulatory CD4+ T subset is critical for FMN survival.
