Úloha míšních TRPV1 receptorů v nociceptivním přenosu a modulační účinky chemokinu CCL2 a agonistů µ-opioidního receptoru / The role of spinal TRPV1 receptors in nociceptive signalling and the modulatory effect of chemokine CCL2 and µ-opioid receptor agonists

The first nociceptive synapse in the spinal cord dorsal horn represents an important site, where nociceptive synaptic transmission can be modulated under pathological conditions. One of the modulatory mechanism involves activation of the transient receptor potential vanilloid 1 (TRPV1) that is expressed on central terminals of primary nociceptive neurons, where it regulates release of neurotransmitters and neuromodulators. Previous studies suggested that changes in TRPV1 activity may be related to effects of chemokine CCL2 (C-C motif ligand 2) and may be also involved in synaptic transmission modulation after µ-opioid receptors (MOP-R) activation. Because CCL2 receptors CCR2 often co-localize with TRPV1 and MOP-R, the goal of this work was to studypossible interactions of these receptors on the pre-synaptic endings of primaryafferents in the spinal cord dorsal horn and their role in nociceptive signalling under pathological conditions. The presented thesis focused on the effect of CCL2 during peripheral neuropathy and its interference with µ-opioid receptor activation. To studysynaptic transmission at the spinal cord level, patch-clamp recordings of excitatory post-synaptic currents (EPSC) in superficial spinal cord dorsal horn neurons in acute lumbar spinal cord slices from rats was used....
