The cell membrane has several functions that are integral to the health of the cell. The functions of the cell membrane include physical and barrier functions as well as regulatory functions. Cell Membrane Functions One function of the cell membrane is to provide the cell with shape and structure...
In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable. In much the same way that doors and windows allow ...
Among the physicochemical cues in the cellular microenvironment that orchestrate cell processes, the different levels of curvature in the extracellular matrix and intrinsic to the tissues play a pivotal role in the spatiotemporal control of key cellular
MT6-MMP has an unpaired cysteine, Cys-532, at its stalk region (linker-2), and this mediates disulfide bond-mediated homo-dimer formation on the cell surface [9]. TM-type MT-MMPs have an insertion of 8–9 amino acids in the catalytic domain, named the MT-Loop (Fig. 1). This is...
Protein phosphorylation participates in the regulation of all fundamental biological processes, and protein kinases have been intensively studied. However, while the focus was on catalytic activities, accumulating evidence suggests that non-catalytic pro
MHC peptide interacts with the T cell receptors, costimulatory molecules interact with T cell-expressed coreceptors, and cytokines are released to polarize the T-cell response [28], thus results in the allergic airway inflammation. The role of DCs in the secondary immune response is further ...

This Review discusses the major advances and changes made over the past 3 years to our understanding of chimeric antigen receptor (CAR) T cell efficacy and safety. Recently, the field has gained insight into how various molecular modules of the CAR in
