Unveiling the Role of Pro-Neurotrophins and p75NTR in Motor Neuron Degeneration

Nerve cells, the messengers of our body, have long branches called axons that depend on their own protein production for growth and function.

Our study explores the interaction between special molecules called Pro-Neurotrophins (proNTFs) and a receptor known as p75NTR, which act like traffic controllers for survival and death signals. We're particularly interested in how these molecules and receptors impact the health of motor neurons, the cells responsible for muscle control, especially in a disease called Amyotrophic Lateral Sclerosis (ALS).

We're on a mission to uncover how proNTFs, released from muscles, influence the processes that keep these neurons healthy. We are aiming to understand how certain signals contribute to the breakdown of motor neurons in ALS.

By using advanced technologies like microfluidic chambers and unbiased screens, we aim to reveal the detailed molecular processes that lead to the weakening of axons and the death of motor neurons. These discoveries could be a game-changer in understanding diseases that affect our nerve cells, particularly ALS, and may open new doors for targeted treatments in the future.
