SANTA ANA, Calif., July 18, 2024 (GLOBE NEWSWIRE) -- NKGen Biotech, Inc. (Nasdaq: NKGN) (“NKGen” or the “Company”), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic and CAR-NK natural killer (“NK”) cell therapeutics, today announced that it will present new biomarker data on SNK01 (autologous non-genetically modified NK cell therapy) in Alzheimer’s disease during a poster presentation at the upcoming Alzheimer’s Association International Conference (“AAIC”) to be held in Philadelphia, PA at the Pennsylvania Convention Center and online from July 28 – August 1, 2024.

NKGen will present data on SNK01’s ability to reduce α-synuclein in Alzheimer’s patients, which is significant given that α-synuclein has been shown to correlate with worse cognitive function in Alzheimer’s disease. Presentation details are as follows:
