Unlabelled: Experimental studies have demonstrated that nutritional changes during development can result in phenotypic changes to mammalian cheek teeth. This developmental plasticity of tooth morphology is an example of phenotypic plasticity. Because tooth development occurs through complex interactions between manifold processes, there are many potential mechanisms which can contribute to a tooth's norm of reaction.

Background And Aims: Pancreatic stellate cells (PSCs) are critical mediators in chronic pancreatitis with an undefined role in acute pancreatitis (AP). PSCs consist of a heterogenous group of cells and are considered interchangeable with pancreatic fibroblasts. This study explored the heterogeneous nature of PSCs by characterizing pancreatic collagen-expressing fibroblasts (PCFs) via lineage tracing in mouse normal and AP pancreas and determining the effect of PCF depletion in AP.

Here, we apply SuperResNET network analysis of dSTORM single-molecule localization microscopy (SMLM) to determine how the clathrin endocytosis inhibitors pitstop 2, dynasore and Latrunculin A alter the morphology of clathrin-coated pits. SuperResNET analysis of HeLa and Cos7 cells identifies: small oligomers (Class I); pits and vesicles (Class II); and larger clusters corresponding to fused pits or clathrin plaques (Class III). Pitstop 2 and dynasore induce distinct homogeneous populations of Class II structures in HeLa cells suggesting that they arrest endocytosis at different stages.

The primary mode of transmission for Chagas disease is vector-borne transmission, spread by hematophagous insects of the subfamily. In Mexico, the triatomine is particularly significant in the transmission of . This study focused on analyzing protein expression and modifications by glycosylation in different regions of the digestive tract of fifth-instar nymphs of .

Background: Interfacial heterogeneity is widely explored to reveal molecular mechanisms of force-mediated pathways due to biased tension. However, the influence of cell density,, curvature, and interfacial heterogeneity on underlying pathways of mechanotransduction is obscure.
Methods: Polydimethylsiloxane (PDMS)-based stencils were micropatterned to prepare the micropores for cell culture.
