Bacterial meningitis is a life-threatening infection that affects more than 2.5 million people annually, according to recent studies. Recently, researchers discovered that Nav1.8+ nociceptors signal immune cells in the meninges via the neuropeptide calcitonin gene-related peptide (CGRP) during infection; this neuroimmune axis suppresses host defenses further increasing the risk of bacterial meningitis. According to a study published in Nature, bacterial meningitis causes pain and headaches … Continue reading Bacterial Meningitis: Study Finds Neuroimmune Axis That Exacerbates Host Defenses
