LA JOLLA\u2014Salk Institute scientist Sreekanth Chalasani \u535a\u58eb<\/a>, has received an award of up to $41.3 million from the Advanced Research Projects Agency for Health (ARPA-H), an agency within the United States Department of Health and Human Services. The funding will allow Chalasani and his team to transform his lab\u2019s sonogenetics discovery\u2014using ultrasound to precisely control mammalian cells\u2014into a potential new therapy for a number of human conditions, such as peripheral neuropathies.<\/p>\n

Sonogenetics<\/a> is an emerging approach that sensitizes specific cell types to ultrasound by equipping them with ultrasound-responsive proteins, enabling precise, noninvasive control. For up to 5.5 years, the ARPA-H award will support a multi-institution collaboration focused on developing core biological tools, next-generation ultrasound delivery systems, and the preclinical evidence needed to move sonogenetics into clinical trials for patients.<\/p>\n

\u201cThis award is a major step toward a long-held goal\u2014a drug-free way to deliver therapy exactly where it\u2019s needed and only when it\u2019s needed,\u201d says Chalasani, Salk professor, sonogenetics developer, and lead principal investigator for the ARPA-H award. \u201cWe are building a platform that pairs engineered ultrasound-sensitive proteins with wearable ultrasound technology, which, unlike conventional pharmaceutical treatments, could let us treat conditions with cellular and temporal control.<\/p>\n

What is sonogenetics?<\/strong><\/h2>\n

Sonogenetics is the application of low-intensity ultrasound to achieve precise, noninvasive control over cellular activity. Chalasani pioneered this concept and coined the term \u201csonogenetics\u201d to describe it. In 2015, his group first identified a protein in the roundworm Caenorhabditis elegans<\/em> that makes cells sensitive to low-frequency ultrasound. When the researchers added this protein to C. elegans<\/em> neurons that didn\u2019t usually have it, they could activate these cells with a burst of ultrasound\u2014the same sound waves used in medical sonograms. The team, along with several others worldwide, has since also demonstrated the ability of sonogenetics to manipulate mammalian cells.<\/p>\n

The ARPA-H award will allow Chalasani and collaborators to move sonogenetics out of the lab and toward the clinic by testing the approach as a therapy for medical conditions such as peripheral neuropathy.<\/p>\n

What will the ARPA-H-funded sonogenetics team build? <\/strong><\/h2>\n

The project will integrate multiple technical tracks to develop an end-to-end therapeutic strategy: a tool kit of ultrasound-sensitive proteins, a noninvasive ultrasound delivery system suitable for long-term use, and the translational evidence needed to support regulatory progression.<\/p>\n

Collaborating teams, listed in the order of workflow from discovery to translation, include:<\/p>\n

    \n
  • Scripps Research<\/strong>\u2014A team led by Nobel Laureate Ardem Patapoutian, PhD, will support the discovery and engineering of ultrasound-sensitive proteins, drawing on deep expertise in mechanosensitive channels.<\/li>\n
  • Boniface Hospital Research\/University of Manitoba<\/strong>\u2014A team led by Paul Fernyhough, PhD, will help define how ultrasound-triggered signals propagate through cellular machinery and drive nerve repair pathways.<\/li>\n
  • Duke University<\/strong>\u2014A team led by Aravind Asokan, PhD, will develop targeted vectors to deliver ultrasound-sensitive proteins to specific cell types in the body, enabling translation of the focused ultrasound control platform.<\/li>\n<\/ul>\n
      \n
    • Massachusetts Institute of Technology Department of Mechanical Engineering (MIT MechE)<\/strong>\u2014A team led by Xuanhe Zhao, PhD, will develop ultrasound delivery systems for relevant targets in both animals and humans.<\/li>\n<\/ul>\n
        \n
      • University of California San Diego<\/strong>\u2014A team led by Nigel Calcutt, PhD, will validate the efficacy of the sonogenetics approach across established paradigms and clinically relevant functional readouts in mammalian systems.<\/li>\n
      • California Medical Innovations Institute (Calmi2)<\/strong>\u2014A team led by Ghassan Kassab, PhD, will support advanced translational validation and clinically relevant assessments in preclinical systems.<\/li>\n
      • SonoNeu<\/strong>\u2014A strategic startup co-founded with General Inception, this team will unify research activities across all sites and help advance the program along a clear regulatory pathway toward FDA evaluation and commercialization.<\/li>\n<\/ul>\n

        From foundational discovery to a translational program<\/strong><\/h2>\n

        Chalasani\u2019s pioneering work on sonogenetics began with experiments in worms, supported by seed funding in 2011 from Salk\u2019s Innovation and Collaboration Grants program, made possible by philanthropists Joan and Irwin Jacobs, co-founder of Qualcomm and former chair of Salk\u2019s Board of Trustees. That early-stage support helped launch an idea that was bold, unproven, and difficult to fund through traditional mechanisms\u2014an approach Salk is designed to champion as part of its commitment to foundational science that enables future therapies and innovations. The new ARPA-H award will now advance sonogenetics toward a clinical proof-of-concept in the periphery.<\/p>\n
