TRPV1-Mediated Crosstalk Between Sensory Neurons and Hematopoietic Stem Cells in Inflammatory Environments

While Andolfo et al. (2021) revealed TRPV1’s role in sickle cell disease pain and vaso-occlusion, they didn’t explore if TRPV1 signaling affects hematopoietic stem cells (HSCs). This research would test whether TRPV1 activation by thermal/chemical stimuli (e.g., capsaicin) modulates HSC proliferation or differentiation via neuropeptide release (e.g., CGRP). Using mouse models of chronic inflammation (e.g., arthritis), we’d combine TRPV1 antagonists with bone marrow imaging to track HSC dynamics. This challenges the view of TRPV1 as purely sensory, proposing it as a neuro-immune bridge. Novelty: Links temperature receptors to stem cell biology—a departure from TRPV1’s established pain-focused roles.
