Axonal degeneration is responsible for disease progression and accumulation of disability in many neurodegenerative conditions. The axonal degenerative process can generate a metastable pool damaged axons that remain structurally functionally viable but fated to degenerate the absence external intervention. SARM1, an NADase depletes energy stores upon activation, central driver evolutionarily conserved program degeneration. We identify potent selective small molecule isoquinoline inhibitor SARM1 recapitulates SARM1-/- phenotype protects from induced by axotomy or mitochondrial dysfunction. inhibition post-mitochondrial injury with rotenone allows recovery rescues already entered state. conclude molecules has potential treat axonopathies peripheral nervous systems preventing allowing functional damaged, viable, axons.

Since the first clinical trials conducted after World War II, chemotherapeutic drugs have been extensively used in clinic as main cancer treatment either alone or an adjuvant therapy before and surgery. Although use of improved survival patients, these are notorious for causing many severe side effects that significantly reduce efficacy anti-cancer patients' quality life. Many widely chemotherapy including platinum-based agents, taxanes, vinca alkaloids, proteasome inhibitors, thalidomide analogs may cause direct indirect neurotoxicity. In this review we discuss on peripheral central nervous systems, neuropathic pain, chemobrain, enteric neuropathy, well nausea emesis.

Abstract Background In response to injury, neurons activate a program of organized axon self-destruction initiated by the NAD + hydrolase, SARM1. healthy SARM1 is autoinhibited, but single amino acid changes can abolish autoinhibition leading constitutively active enzymes that promote degeneration when expressed in cultured neurons. Methods To investigate whether naturally occurring human variants might disrupt and potentially contribute risk for neurodegenerative disease, we assayed enzymatic activity all 42 rare alleles identified among 8507 amyotrophic lateral sclerosis (ALS) patients 9671 controls. We then intrathecally injected mice with virus expressing constructs test capacity an ALS-associated variant neurodegeneration vivo. Results Twelve out missense or small in-frame deletions exhibit constitutive NADase activity, including more than half those are unique ALS occur multiple patients.

Neuroinflammation and necroptosis are major contributors to neurodegenerative disease, axon dysfunction degeneration is often an initiating event. SARM1 the central executioner of pathological degeneration. Here, we demonstrate functional mechanistic links among these three pro-degenerative processes. In a neuroinflammatory model glaucoma, TNF-α induces SARM1-dependent degeneration, oligodendrocyte loss, subsequent retinal ganglion cell death. also triggers in sensory neurons via noncanonical necroptotic signaling mechanism. MLKL final canonical necroptosis; however, axonal necroptosis, does not directly trigger Instead, loss survival factors NMNAT2 STMN2 activate NADase activity, which leads calcium influx Hence, findings define specialized form necroptosis. The demonstration that signals can act locally stimulate identifies therapeutically targetable mechanism by neuroinflammation disease.

Attempts to develop neuroprotective treatments for neurodegenerative disorders have not yet been clinically successful. Axonal degeneration has recognized as a predominant driver of disability and disease progression in central nervous system (CNS) diseases such amyotrophic lateral sclerosis (ALS), multiple sclerosis, Parkinson's disease, peripheral (PNS) chemotherapy-induced, diabetic, inherited neuropathies, ocular disorders, glaucoma. In recent years, sterile alpha TIR motif containing 1 (SARM1) emerged the first compelling axonal-specific target therapeutic intervention. this review, we discuss role axonal with focus on SARM1 discovery its intrinsic enzymatic function. Establishment neurofilament light chain (NfL) reliable biomarker damage, availability an ultrasensitive method measuring NfL plasma or serum, provide translational tools make development protective, inhibitors viable approach treat disorders.
