ZyVersa Therapeutics Announces Article in Peer-Reviewed Journal, Ecotoxicology and Environmental Safety, Linking Air Pollution with Development and Progression of Chronic Kidney Disease That Can Be Attenuated by Inhibiting Inflammasome NLRP3 Activation


  • Despite decades of effective environmental policy and improved air quality in the US, air pollution remains the greatest environmental health risk factor, contributing to 100,000 to 200,000 incremental deaths annually, primarily from fine particulate matter (PM2.5) derived from pollutants including vehicle and industrial emissions from fuel and biomass combustion, cigarette smoke, volcanos, fires, and desert dust.
  • PM2.5 is inhaled into the lungs, spreading through the bloodstream to other organs, especially the kidney, which accumulates it during glomerular filtration, where it triggers NLRP3 inflammasome activation resulting in damaging inflammation and cell death (pyroptosis) leading to chronic kidney disease and its progression.
  • ZyVersa is developing Inflammasome ASC Inhibitor IC 100 which can inhibit up to 12 different inflammasomes (including NLRP3 inflammasomes) and their associated ASC specks which perpetuate damaging inflammation.

WESTON, Fla., Nov. 06, 2023 (GLOBE NEWSWIRE) -- ZyVersa Therapeutics, Inc. (Nasdaq: ZVSA, or “ZyVersa”), a clinical stage specialty biopharmaceutical company developing first-in-class drugs for treatment of inflammatory and renal diseases, announces publication of an article in the peer-reviewed journal, Ecotoxicology and Environmental Safety, demonstrating that inhibiting NLRP3 inflammasomes can attenuate kidney damage and dysfunction associated with the environmental pollutant, PM2.5.

In the paper titled, “PM2.5 induces renal tubular injury by activating NLRP3-mediated pyroptosis,” the authors conducted studies in a mouse model exposed to high concentrations of ambient PM2.5 for 12 weeks, and in a mouse kidney cell line. Following are key findings reported in the paper:

  • PM2.5 exposure leads to kidney structural changes and functional impairment.
  • Inflammasome NLRP3-induced Inflammation and pyroptosis were increased in PM2.5-exposed kidney tissues.
  • Inhibiting the inflammasome NLRP3 pathway, including downstream caspase-1, rescued the kidneys from PM2.5-induced cell death.

The authors stated, “We further provided evidence that NLRP3-mediated pyroptosis plays critical roles in the progression of kidney injury induced by PM2.5 exposure. Inhibiting the activation of NLRP3 inflammasome can remarkably protect the renal tubular epithelial cells from PM2.5-induced proptosis.” To read the article, Click Here.

“The research published in the Journal, Ecotoxicology and Environmental Safety, reinforces other published data demonstrating that inhibiting NLRP3 inflammasomes can attenuate kidney damage and dysfunction of multiple causes, now including kidney damage associated with the environmental pollutant, PM2.5,” commented Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO and President. “This research provides increasing support for inflammasome inhibition as a promising treatment option for kidney disease, a major health problem affecting over 35 million adults in the United States. ZyVersa is developing Inflammasome ASC inhibitor IC 100. Unlike NLRP3 inhibitors, designed to inhibit formation of one inflammasome to block initiation of the inflammatory cascade, IC 100 was designed to inhibit multiple types of inflammasomes and their associated ASC specks to uniquely block both initiation and perpetuation of damaging inflammation.” To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here.

About Inflammasome ASC Inhibitor IC 100

IC 100 is a novel humanized IgG4 monoclonal antibody that inhibits the inflammasome adaptor protein ASC. IC 100 was designed to attenuate both initiation and perpetuation of the inflammatory response. It does so by binding to a specific region of the ASC component of multiple types of inflammasomes, including NLRP1, NLRP2, NLRP3, NLRC4, AIM2, Pyrin. Intracellularly, IC 100 binds to ASC monomers, inhibiting inflammasome formation, thereby blocking activation of IL-1β early in the inflammatory cascade. IC 100 also binds to ASC in ASC Specks, both intracellularly and extracellularly, further blocking activation of IL-1β and the perpetuation of the inflammatory response that is pathogenic in inflammatory diseases. Because active cytokines amplify adaptive immunity through various mechanisms, IC 100, by attenuating cytokine activation, also attenuates the adaptive immune response.
