Abstract

The rules of T cell positioning within virus-infected respiratory tract tissues are poorly understood. We therefore marked cervical lymph node or spleen cells from Sendai virus (SeV) primed mice and transferred lymphocytes to animals infected with SeV expressing an enhanced green fluorescent protein (SeV-eGFP). Confocal imaging showed that when T cells entered a field of infected respiratory tract epithelium, they assumed a spatial distribution that maximized distances between each donor cell and its nearest neighbor. We therefore hypothesized that lymphocytes repelled one another by altering their chemokine/cytokine microenvironment. Subsequent in vitro tests confirmed that when SeV-primed ..
