Inflammation and Synaptic Plasticity

Neuroinflammation

A major hallmark of brain diseases is neuroinflammation. We study how immune mediators affect synaptic plasticity. Particularly, our work focuses on better understanding how these factors inflammatory cytokines influence intracellular calcium stores, i.e. the spine apparatus organelle, and how these changes alter the ability of neurons to express associative and homeostatic synaptic plasticity. The concept of neurocoagulation at the neuroimmunological synapse and its relevance for tissue-probe-interactions is an emerging topic in this context.
