Cell walls primary function is mechanical support. It acts like a skeletal framework of the plants. Cell wall is tough and has high tensile strength. Still plant cell is fully permeable to water and solutes. Pl

The cell wall of Gram-positive bacteria is a complex assemblage of glycopolymers and proteins. It consists of a thick peptidoglycan sacculus that surrounds the cytoplasmic membrane and that is decorated with teichoic acids, polysaccharides, and proteins.

By contrast, the function of plasmacytoid DCs is largely innate and restricted to the detection of viral infections and the production of type I interferon. Here, we discuss genetic models of mouse DC development and function that have aided in correlating ontogeny with function, as well as how...

Another microscope—the atomic force microscopy (AFM)-gives unique possibility to visualize structure, topography (Figure 4) and examine mechanical properties of cells (e.g., adhesion force distribution, cells stiffness—Young's modulus as a biomarker of the relative metastatic potential).This method...
A classification procedure is called “parametric” if the general form of the feature probability density function is known for each class. The actual values of their parameters (e.g., mean and variance) are usually not known beforehand and will be estimated. In this case, the most likely ...
Adult stem cells maintain regenerative tissue structure and function by producing tissue-specific progeny, but the factors that preserve their tissue identities are not well understood. The small and large intestines differ markedly in cell composition and function, reflecting their distinct stem cell pop...
function in MZ B cells depends on its ability to undergo autoproteolytic cleavage and signaling via Gα13and ARHGEF1. Red blood cell expression of the CD97 ligand CD55 is required for MZ B cell homeostasis. Applying a pulling force on CD97-transfected cells using an optical C-trap and ...
