Official title: Sensory neuron fibroblast crosstalk in knee osteoarthritis

Funded at Wake Forest University Health Sciences · NIH-11453379 · Data updated 2026-11-12

This grant tests how nerve signals and joint cells interact in knee osteoarthritis, with a focus on CGRP pathways and how they affect pain and joint damage.

Who could benefit from this research

Could help

Patients with knee osteoarthritis or related joint pain could benefit from future therapies arising from this research.

Less likely to help

Early-stage preclinical work may not yet translate to immediate patient benefits.

What this research studies

We will study how signals from sensory nerves (like CGRP) affect different cell types in the knee joint over time to see how pain and joint damage develop in osteoarthritis. Using animal models and cellular studies, the project will explore how blocking CGRP or altering its signaling changes pain behavior, inflammation, and tissue remodeling. The researchers aim to map which cells respond to CGRP and whether effects differ between males and females. The work could reveal why some treatments help with pain but worsen tissue changes in certain models. Findings could guide future therapies that target nerve–joint interactions to relieve pain while protecting the joint.

Why it matters

Potential benefit: If successful, this work could lead to better-targeted treatments for knee OA pain that minimize joint damage.

How similar studies have gone: Prior studies showed CGRP-related pain reduction in some models, but long-term and sex-specific effects remain mixed, making this research novel in knee OA.
