This change in gene expression leads to increased biofilm formation in the bacterial population through a phenomenon now known as Contact-Dependent Signalling. Furthermore, the T6SS in V. cholerae is active in biofilms, enabling a cell expressing T6SS to kill nearby cells which do not have the specific immunity. [5]
Cellular thermal shift assay (CETSA ®) [29] is a biophysical technique applicable on living cells as well as tissue biopsies. CETSA ® is based on the discovery that protein melting curves can also be generated in intact cells and that drug binding leads to very significant thermal stabilization of proteins. Upon denaturation, proteins are ...
In chemistry, charge-transfer (CT) complex, or electron donor-acceptor complex, describes a type of supramolecular assembly of two or more molecules or ions. The assembly consists of two molecules that self-attract through electrostatic forces, i.e., one has at least partial negative charge and the partner has partial positive charge, referred ...
When collision is unavoidable, a different phenomenon occurs whereby growth of the cells of the culture itself eventually stops in a cell-density dependent manner. [ 2 ] Both types of contact inhibition are well-known properties of normal cells and contribute to the regulation of proper tissue growth, differentiation, and development.
Cell–cell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the ...
In dosimetry, linear energy transfer (LET) is the amount of energy that an ionizing particle transfers to the material traversed per unit distance. It describes the action of radiation into matter. It is identical to the retarding force acting on a charged ionizing particle travelling through the matter. [ 1 ]
One classification system involves the distinction between calcium-independent CAMs and calcium-dependent CAMs. [7] The Ig-superfamily CAMs do not depend on Ca 2+ while integrins, cadherins and selectins depend on Ca 2+. In addition, integrins participate in cell–matrix interactions, while other CAM families participate in cell–cell ...
Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments.
