Recording of electrophysiological activity from dorsal horn neurons in acute spinal cord slices with patch-clamp technique.
The main research interest of our department is to study mechanisms of pain and to explore new possibilities of pain treatment, especially in chronic states. Our experimental work is concentrated on the modulation of nociceptive information at the spinal cord level that is the relay center between the periphery and the higher brain areas. Our goal is to study these modulatory mechanisms in order to improve therapy for pain conditions, such as allodynia, hyperalgesia, neuropathic and cancer related pain. Our focus is on the role of TRPV1 receptors and inflammatory cytokines. In our research we use mainly electrophysiological, immunohistochemical and behavioral methods. In addition, we finalize another project directed towards the role of thyroid hormones (THs) and omega-3-polyunsaturated fatty acid (n-3 PUFA) in the physiology of cardiac and skeletal muscles. Models of hyper- and hypothyroid status are used to analyze potential influence of n-3 PUFA on the induced pathological changes.
Projects
Scientists from the Department of Functional Morphology in collaboration with colleagues from The University of Texas showed that paclitaxel induced pain is mediated by TRPV1 and TLR4 receptors.

N-acylphosphatidylethanolamine (NAPE), as the precursor of anandamide, an endogenous agonist of TRPV1 and cannabinoid receptors, could play a role in modulation of nociceptive signalization in the spinal cord.

TRPV1 receptors are present on small diameter dorsal root ganglia neurons, that are involved in pain perception. Dorsal root ganglia neurons on histological slide stained for the presence of TRPV1 receptors (red) and parvalbumin (green).
For the study of cardiac and skeletal muscles histochemical and immunocytochemical staining of tissue sections is used. On the picture skeletal muscle sections stained for specific muscle proteins is shown enabling us quantitative analysis of different muscle fiber types (převzato z práce Soukup et al., Physiol Res 61: 575-586, 2012).
