An analysis of nerve growth factor (NGF) receptor expression and density in human sural nerve biopsies was performed by immunocytochemistry with a murine monoclonal antibody against the human NGF receptor. Quantitative assessment of immunostaining density was made by histospectrophotometry on frozen sections. Although there was enhanced expression of NGF receptor within endoneurium in all patients with clinical neuropathies, expression was highest in nerves with axonal disease, consistent with the proposal that disruption of axon-Schwann cell interactions triggers the re-expression of the NGF receptor. These results with human nerves, together with previous studies with animal models, suggest that NGF and NGF receptor play important roles in the general response to neuronal injury.

Background And Objectives: Breast cancers (BCs) of patients with paraneoplastic neurologic syndromes and anti-Yo antibodies (Yo-PNS) overexpress human epidermal growth factor receptor 2 (HER2) and display genetic alterations and overexpression of the Yo-onconeural antigens. They are infiltrated by an unusual proportion of B cells. We investigated whether these features were also observed in patients with PNS and anti-Ri antibodies (Ri-PNS).

Aim: Sympathetic overactivation may lead to severe ventricular arrhythmias (VAs) post-myocardial infarction (MI). The superior cervical ganglion (SCG) is an extracardiac sympathetic ganglion which regulates cardiac autonomic tone. We aimed to investigate the characteristics and functional significance of SCG on neuro-cardiac communication post-MI.

Brain-derived neurotropic factor (BDNF) is expressed by skeletal muscle as a myokine. Our previous work showed that the active precursor, proBDNF, is the predominant form of BDNF expressed in skeletal muscle, and that following skeletal muscle injury, proBDNF levels are significantly increased. However, the function of the muscle-derived proBDNF in injury-induced inflammation has yet to be fully understood.

It has been proposed that bone marrow contributes to the pathogenesis of arteriosclerosis. Nerve growth factor receptor (NGFR) is expressed in bone marrow stromal cells; it is also present in peripheral blood and ischemic coronary arteries. We hypothesized that bone marrow-derived NGFR-positive (NGFR) cells regulate arterial remodeling.

Vascular obstruction often causes inadequate oxygen and nutrient supply to the brain. This deficiency results in cerebral ischemic injury, which significantly impairs neurological function. This review aimed to explore the neuroprotective and regenerative effects of nerve growth factor (NGF) in cerebral ischemic injury.
