When encephalitogenic T cells collaborate with microglia in multiple sclerosis.

Area of Science:

• Neuroimmunology
• Neuroinflammation
• Multiple Sclerosis Pathogenesis

Background:

• Immune cells, including microglia and T cells, play key roles in the central nervous system (CNS).
• In multiple sclerosis (MS), interactions between activated microglia and infiltrating T cells can exacerbate CNS injury.
• This crosstalk involves complex molecular signaling pathways.

Purpose of the Study:

• To review the mechanisms and consequences of T cell-microglia interactions in MS.
• To discuss the translation of preclinical findings to human MS.
• To explore therapeutic strategies targeting these interactions.

Main Methods:

• Review of in vitro experiments and animal models of T cell-microglia interactions.
• Analysis of cell-surface molecules, cytokines, and neurotoxic factors involved.
• Discussion of challenges in translating preclinical data to human MS.

Main Results:

• T cell-microglia interactions amplify neuroinflammatory and neurodegenerative processes in MS.
• Specific molecular crosstalk mechanisms contribute to disease exacerbation.
• Preclinical models provide insights into disease mechanisms but face translation challenges.

Conclusions:

• Understanding T cell-microglia crosstalk is crucial for MS pathogenesis.
• Modulating these interactions presents a promising therapeutic avenue for MS.
• Further research is needed to bridge preclinical findings with clinical applications in MS treatment.
