It is crucial to comprehend protein misfolding and aggregation in the domains of biomedicine, pharmaceuticals, and proteins. Amyloid fibrils are formed when proteins misfold and assemble, resulting in the debilitating illness known as "amyloidosis". This work investigates lysozyme fibrillation with pluronics (F68 and F127). The effect of pluronics on protein aggregation and fibrillation has been studied mechanistically using a combination of calorimetric and spectroscopic techniques. TEM images and the ThT binding experiment were used to analyze the conformation of protein fibrils, and the results showed that pluronics accelerated the fibrillation process. When pluronics interact with protein at different stages of fibrillation, their pre- and postmicellar concentrations show a decrease in ΔHm° value as the time of incubation increases. This indicates the formation of amorphous aggregates due to which endothermic enthalpy is observed. As a consequence, it was investigated if these generated aggregates can also act as drug delivery vehicle; therefore, the work was carried out with 5-fluorouracil and cytarabine. The endothermic enthalpy of interaction suggests that hydrophobic interaction is more prevalent when cytarabine is employed with protein fibrils, whereas the electrostatic interaction is more prevalent when 5-fluorouracil is combined with it. The former drug, however, showed a greater adsorption than the latter on the surface of protein fibrils. It is therefore determined that 5-fluorouracil has relatively significant adsorption on fibril surfaces, whereas cytarabine has weak adsorption and is easily desorbed in cells. Consequently, the combination of LFF127 and 5-FU is lethal to malignant cells. The drug encapsulation and delivery aspect of protein fibrils/aggregates needs further exploration.
