Abstract (original English)

Background/Objectives: Inflammatory processes, both acute and chronic, encompass a wide range of autoimmune, metabolic, and neurodegenerative conditions. Conventional treatments, primarily anti-inflammatories and immunosuppressants, provide partial relief but are often hampered by adverse effects and limited durability. Mesenchymal stem cells (MSCs) have emerged as a powerful new treatment due to their immunomodulatory and anti-inflammatory properties, primarily mediated through their secretome, which is a complex mixture of bioactive factors. Secretome-based therapeutic strategies show strong potential for controlling inflammation, mitigating oxidative stress, and supporting tissue regeneration and repair. However, the therapeutic efficacy of MSCs' secretome is subject to modification by concurrent anti-inflammatory drug regimens used in clinical settings. Methods: To evaluate the effect of combinatorial treatment strategies on the secretome of the MSCs, we employed an in vitro retinal inflammation model to investigate whether the exposure of the MSCs to five representative anti-inflammatory drugs (ketorolac, diclofenac, α-lipoic acid, N-acetyl-L-cysteine, and nicotinamide) impacts the functionality of the resulting secretome. Specifically, we evaluated the effect of the above-mentioned drugs on the anti-inflammatory properties of the secretome in relation to the secreted leve
