EFFECT OF SEROTONIN ADSORVED TO POLYETHYLENE GLYCOL MICROSPHERES ON HUMAN CELL VIABILITY

Serotonin is a biogenic amine that induces metabolic effects in various cell types, acting on the immune, central nervous, and gastrointestinal systems. When synthesized, it is released and acts on its receptors. Polyethylene glycol (PEG) is a hydrophilic synthetic polymer, useful in various chemical, biological, and pharmaceutical functions due to its numerous properties. This material has been used to produce microparticles, which act as a drug delivery system and have several advantages, including the ability to encapsulate multiple molecules, reduced toxicity, and modified release effectiveness.
