Our triple labelling method allows the AChE and AChR distributions and the nerve endings to be stained in the same preparation. This method which provides a detailed visualization of the synaptic contacts and is capable of revealing a weak AChE activity is particularly valuable in studies of synaptogenesis.

Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and progressive bulbar palsy, involve loss of muscle control resulting from death of motor neurons. Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function.

The recent identification of Piezo ion channels demonstrating a mechano-sensitive impact on neurons revealed distinct Piezo-1 and 2 types. While Piezo-1 predominates in neurons linked to non-sensory stimulation, such as pressure in blood vessels, Piezo-2 predominates in neurons linked to sensory stimulation, such as touch. Piezo-1 and 2 have a major bidirectional impact on transient receptor potential (TRP) ion channels, and TRPs also impact neurotransmitter release.

Alpha-synuclein (ASyn), a marker of Parkinson's disease (PD) and other neurodegenerative processes, plays pivotal roles in neuronal nuclei and synapses. ASyn and its phosphorylated form at Serine 129 (p-ASyn) are involved in DNA protection and repair, processes altered in aging, neurodegeneration, and cancer. To analyze the localization of p-ASyn in skin biopsies of PD patients and melanoma.

Introduction In their routine practice, dentists frequently encounter dentinal hypersensitivity, which is caused by the pulpal nerves' increased excitability due to fluid movement in the dentinal tubules. It is treated in-office using dentin desensitizers, which reduce hypersensitivity by obstructing the open tubules or desensitizing the free nerve endings present within the tubules. However, no substance or treatment plan has ever been proven to be the gold standard for the efficient treatment of dentinal hypersensitivity.

Aging disrupts multiple homeostatic processes, including autophagy, a cellular process for the recycling and degradation of defective cytoplasmic structures. Acute treatment with the autophagy inhibitor chloroquine blunts the maximal forces generated by the diaphragm muscle, but the mechanisms underlying neuromuscular dysfunction in old age remain poorly understood. We hypothesized that chloroquine treatment increases the presynaptic retention of the styryl dye FM 4-64 following high-frequency nerve stimulation, consistent with the accumulation of unprocessed bulk endosomes.
