About

Sandra Pierre is a neuroscientist whose research centers on the molecular mechanisms of pain processing in the spinal cord, with a particular focus on lipid signaling and protein regulation. Her work has been instrumental in uncovering how sphingosine 1-phosphate (S1P)—a bioactive lipid well-known for its roles in cell survival and migration—modulates nociceptive transmission in the central nervous system. In her highly cited 2008 study (51 citations), Pierre provided some of the first evidence that S1P directly influences spinal nociceptive processing, opening a new avenue for understanding pain signaling beyond classical neurotransmitter systems. She has also made significant contributions to the study of protein associated with Myc (PAM), a giant E3 ubiquitin ligase, using innovative toponomics approaches like multiepitope ligand cartography (MELC) to map its functional interactions during pain processing (30 citations). This work advanced the understanding of how ubiquitin-mediated protein regulation shapes synaptic strength in the spinal cord. Pierre’s research bridges molecular cell biology and systems neuroscience, offering potential targets for novel pain therapies. Her studies remain foundational for researchers exploring lipid mediators and ubiquitin signaling in chronic pain.
