Full textHeating represents a promising approach to induce neurite outgrowth and neuronal function recovery. In previous studies, protocols with different temperatures (from 38°C to 50°C) and durations (from milliseconds to several days) could induced differentiation of different cell types like Xenopus laevis oocytes, cultured mammalian cells, neurons, stem cells and cancer cells. This effect has been attributed to changes in cell membrane capacitance and in ion channel properties, but the underlying mechanism remains so far unknown. The present project was aimed to investigate the eventual modifications, induced by two approaches of thermal stimulation, on the behaviour of a model of dorsal root ganglion (DRG) neurons, the F-11 cell line, previously characterized in our laboratory. These cells could express ion channels and cell membrane receptors consistent with those of sensory neurons and could be employed as a good model to study neuronal proliferation and differentiation mechanisms. Initially, to test if heating could effectively induce differentiation of our cellular model, we performed experiments of bulk stimulation: cells were placed in an incubator at different time and temperature combinations for two consecutive days. Thus, morphological and functional analysis were performed to investigate neuronal differentiation until 8 days. Results showed a significant difference in neurite elongation and in electrophysiological properties (resting membrane potential, Na+ and K+ current density and action potential frequency) in samples maintained at 41,5°C for 30 minutes versus 37°C samples. An intracellular Ca2+ signal analysis evoked by Capsaicin was performed to verify the involvement of TRPV (Transient Receptor Potential Vanilloid) channels in the effects of heating. Results showed that the Ca2+ signal was higher in heated cells compared to the control, suggesting that the treatment could increase the expression and/or the properties of TRPV1 channels, which are permeable to Ca2+. Moreover, we performed a lactate dehydrogenase activity (LDH) assay to verify if the treatment could induce cell stress and results showed that heat had no detrimental effects on F-11 cells. Considering these results, we investigated the effects of a scalable thermal stimulation method, established by irradiating Prussian Blue nanoparticles (PBNPs) with a near infrared laser. A disk of PBNPs-PVA was placed on the outer surface of the petri dish in which the cells were seeded, avoiding a direct contact between the material and the cells, and it was irradiated by a near infrared laser to increase culture medium temperature to 41,5°C. Neurite elongation was significantly increased in irradiated cells compared to non-irradiated control cells and significant differences were also observed during the functional analysis by patch-clamp technique. To verify if the effects on cellular properties could be maintained for a longer period, we performed a functional investigation also on heated and irradiated cells after 12 days in culture. Results showed that F-11 cells could maintain a differentiated phenotype also after 12 days in culture. The heating techniques used in literature could modify neuron excitability and had effects on cell morphology and staining, but the functional effects has not been reported so far. Moreover, primary cells represent an ideal model to study sensory neurons, but their availability is limited. The use of an immortalized cell line allowed to perform a functional study on the effects of heating, and the results demonstrated that a targeted thermal stimulation could be a promising approach to induce cell differentiation and support the future application of this method as a strategy to modify neuronal behaviour in vivo.

Full textThe neural machinery underlying sensory and motor processes in the primate brain remain largely unclear. Decades of neurophysiological literature evidenced the presence of distinct neuronal properties in many nodes of the cortical grasping network, from purely motor neurons encoding motor goals to sensorimotor neurons responsive to visually presented objects, observed actions or both. The attribution of these functional properties to specific neuronal classes, such as inhibitory interneurons or pyramidal neurons, would be crucial to achieve a better understanding of the motor-based perceptual and cognitive functions stemming from the inner organization of the motor system. To date, several studies showed that cortical neurons can be identified by jointly considering a variety of features of their spike waveform and firing properties, but the specific relation between physiologically characterized neuronal classes and their coding properties remains unclear, especially in areas of the primates’ motor system. To address this issue, here we studied the features of extracellularly recorded spikes of 355 well-isolated single neurons. Neurons were sampled from 5 hemispheres of 3 macaque monkeys while they performed or observed an experimenter performing, a reaching-grasping go/no-go task with three different objects as targets. Single neuron activity was recorded from anterior intraparietal area AIP (n=86), ventral premotor area F5 (n=106) and pre-supplementary motor area F6 (n=163). First, we performed an unsupervised clustering of spike waveforms that reliably dissociated 3 clusters. We found that physiologically-identified classes of cells, unevenly distributed across the investigated areas, carry distinct visuomotor signals. Broadly spiking neurons are prevalent in area F6 and exhibit a balanced amount of facilitated and suppressed activity during action execution and observation. In contrast, narrow spiking neurons are mostly facilitated by visual signals and show greater mutual modulation of their motor and visual response during one’s own and others’ action, particularly in areas AIP and F5. These findings shed light on the cellular mechanisms underlying local processing of sensorimotor information for planning and executing grasping actions and for processing others’ observed action. Further studies may unravel the contribution of larger cortico-subcortical brain network to the mechanisms elucidated by the present work.
