Deletion of Lymphatic PD‐L1 Protects Mice From Severe Autoimmune Encephalitis

Key Points

The research aims to explore the role of lymphatic PD-L1 in autoimmune encephalitis and its effects on disease severity.
Investigated lymphatic PD-L1 expression in cribriform plate and cervical lymph nodes
Deleted PD-L1 from lymphatic endothelial cells in a mouse model
Monitored disease symptoms and brain infiltrate of T cells
Deletion of lymphatic PD-L1 significantly reduced autoimmune encephalitis symptoms
Increased brain infiltration of regulatory CD8+ Foxp3+ T cells observed after deletion
Findings suggest lymphatic PD-L1 plays a critical role in disease progression

Abstract

Lymphatic endothelial cells at the cribriform plate and in brain-draining cervical lymph nodes express PD-L1 during autoimmune encephalitis. Unexpectedly, deletion of lymphatic PD-L1 expression ameliorates disease symptoms and is associated with increased brain infiltration of regulatory CD8+ Foxp3+ T cells.
