Lecture title: Regenerative medicine for the treatment of MS: Enhancing repair to prevent progression Front Row lecture with Luke Lairson, PhD Description: Multiple sclerosis (MS) is a debilitating autoimmune disease that disrupts the central nervous system, causing symptoms like muscle weakness, cognitive challenges and a gradual loss of function that current treatments cannot fully repair. MS arises when the immune system attacks the myelin sheath, the protective layer insulating neurons. Scripps Research chemistry professor Luke Lairson will discuss his research on the body’s natural repair pathways—specifically those that activate endogenous stem cells to restore myelin. His work aims to develop therapies that complement existing therapeutic approaches and halt MS progression. ABOUT SCRIPPS RESEARCH Scripps Research is an independent, nonprofit biomedical institute based in La Jolla, California, and ranked one of the most influential in the world for its impact on innovation.

The San Diego River Artists’ Alliance (SDRAA) will exhibit work celebrating the many stories of the San Diego River and its ecosystem in a show titled “One River, Many Stories” at Grossmont College Hyde Art Gallery March 24 - April 24, 2025. The opening reception is on Tuesday, March 25 at 4 p.m. - 6 p.m. Meet the artists again on April 10 from 2-4 p.m. A portion of the sales will be donated to the San Diego River Park Foundation (SDRPF). The San Diego River Artists’ Alliance (SDRAA) is a collective of eighteen visual and 3D artists dedicated to spending time along the San Diego River from its source in mountains near Julian to the ocean. Time and experience along the river create the stories the artists retell in their artwork, celebrating its history, beauty and promise. SDRAA encourages the public to connect with the variety of experiences available along the river. Twelve artists will display work at the Grossmont College Hyde Art Gallery. The artists include Joan Boyer, Sue Britt, Cathy Coverley, Gloria Chadwick, Vicky DeLong, Kenda Francis, Jodie Hulden, Natasha Papousek, Susan Osborn, Janet Wytrych, Kathryn Gail Ackley, and Louis Russell. The work includes acrylic, photography, mixed media, glass, watercolor, oil, fiber arts and paper. The exhibit continues in the Patterson Window with seven cyanotype scrolls by Louise Russell. One scroll is the river’s voice and the others are storytellers voices. SDRAA is working alongside the San Diego River Park Foundation (SDRPF) to support its long-term vision of creating a 52 mile park system the length of the river. SDRAA began in 2021 and has participated in several SDRPF events such as RiverFest and sponsored hikes.
