The role of thr kallikrein-kinin system to functional and structural impairment if network activity in multiple sclerosis


Neuronal connectivity and network functions are important for the understanding of multiple sclerosis and its animal models – particularly ion channels play a key role. We established a combination of electrophysical and behavioural techniques to characterize neuronal properties in multiple sclerosis (MS) disease models in vitro and in vivo. We identified a transient period of increased excitability in the thalamocortical neuronal network in the course of inflammatory and demyelinating events. Preliminary data point to specific K+ channels, cytokines and components of the kallikrein-kinin system (KKS) as modulators of neuronal hyperexcitability in animal models of MS. In this funding period, we aim to investigate how the KKS influences MS pathophysiology and to identify the underlying cellular and neuronal network effects. In addition, we aim to establish components of the KKS as possible human biomarkers for different forms of MS and effector channels of KKS signaling as new potential therapeutic targets. Our central questions are::

    1. Can kininogen and KLKs influence MS pathophysiology and what are their cellular and neuronal network effect?
    2. Are serum kininogen levels influenced by neuronal network functions?
    3. Kininogen depositions are found in active MS lesions in close contact to neurons. Are these depositions influencing their function and thus modify the course of disease?

One drug – different effects: Metabolism of immune cells influences mode of action and could be an indicator for side effects
Muenster – One person can eat large amounts of pasta and still be a small dress size while another looks at a piece of chocolate and puts on weight: metabolism varies between individuals – and this goes beyond a subjective feeling. What is apparent in the overall organism also applies to each cell: the metabolism […]...more
