Chemotherapy-treated mice that received the peptide showed faster restoration of tissue function, lower inflammatory markers, and better physical performance than untreated controls
In vivo, extracellular KYNA inhibits NMDA- and QA-induced excitotoxic depolarizations in the rat cortex, demonstrating that KYNA accumulation can protect neurons not only via NMDAR antagonism but potentially through additional molecular targets [87]
Another potential issue is diabetic retinopathy, especially in patients with type 2 diabetes who experience rapid changes in blood sugar levels
The peptide functions as a precision senolytic agent by competing with endogenous FOXO4 for p53 binding, releasing the tumor suppressor protein to trigger apoptosis specifically in cells that have accumulated the senescence-associated secretory phenotype (SASP) markers
