Aldh1l1-Cre/ERT2 Drives Flox-Mediated Recombination in Peripheral and CNS Infiltrating Immune Cells in Addition to Astrocytes During CNS Autoimmune Disease.

ABSTRACT:

Introduction

The transgenic murine Cre/loxP system is deployed to investigate the role of central nervous system (CNS) cell-specific gene alterations in both healthy conditions and models of neurologic disease. The Aldh1l1-Cre/ERT2 line is widely used to target astrocytes with high coverage and specificity within the CNS. Specificity outside the CNS, however, has not been well-characterized, and Aldh1l1-Cre/ERT2-mediated recombination within the spleen has been reported. In many CNS diseases, infiltrating immune cells from the periphery drive or regulate pathogenesis. We tested whether flox-mediated recombination from Aldh1l1-Cre/ERT2 occurs in immune cells in addition to astrocytes and whether these cells traffic from the spleen into the spinal cord during experimental autoimmune
