Animal Study on tol-aLN Implantation
In a study using animal models of multiple sclerosis (EAE), implantation of tol-aLN reduced disease severity even in later stages. This was associated with the production of antigen-specific Foxp3+ Treg cells, which moved to various body tissues including the CNS. It also suppressed inflammatory B cells and altered CNS B cells towards a regulatory state, with single-cell transcriptomics indicating reduced interferon activity and improved microglial conditions.

Why it matters
These findings suggest a potential mechanism for immune system modulation in multiple sclerosis that could lead to innovative therapies. However, the research is confined to animal models without proven effectiveness in humans.
What this does not prove
The findings are restricted to animal models and do not establish any translation to human multiple sclerosis efficacy.
