Growth kinetics and power laws indicate distinct mechanisms of cell-cell interactions in the aggregation process

Fatty acid-based polymeric micelles to ameliorate amyloidogenic disorders

“…Motivated by the experimental observations, we further investigated how the insulin fibrillation process is influenced by the presence of FA moieties in the FABC micelles based on a theoretical framework of diffusion-limited aggregation. [50][51][52][53] We first studied the aggregation process in the absence of FABC micelles. In our model, we consider "N" the number of insulin monomers randomly deposited on a (L × L) lattice system.…”

Inertial effect on evasion and pursuit dynamics of prey swarms: the emergence of a favourable mass ratio for the predator–prey arms race

“…Swarming of insects, flocking of birds, schooling of fishes, and migration of coordinated cells are a few examples of various collective behaviours observed in nature. [1][2][3][4][5][6][7][8][9][10] A variety of reasons have been suggested behind the origin of collective animal motion, such as searching for food, finding new habitat, mating, and reproduction, etc. 1,11,12 Another important reason is the defensive strategy often opted by the prey to stay in a group to protect themselves from predator attacks.…”

Cholate-conjugated cationic polymers for regulation of actin dynamics

“…The actin cytoskeleton controls cell shape, and events like cell division, migration, adhesion, aggregation, and organelle movements; 1,2 these biological phenomena are necessary for cell survival. 3,4 Actin has a nucleotide binding cleft in its core. Actin monomers or G-actin when bound to adenosine triphosphate (ATP), spontaneously polymerize in right-handed double helices known as filamentous actin or F-actin.…”
