Targeted-esterase induced dye loading (TED) supports the analysis of intracellular calcium store dynamics by fluorescence imaging. The method bases on targeting of a recombinant Carboxylesterase to the endoplasmic reticulum (ER), where it improves the local unmasking of synthetic low-affinity Ca2+ indicator dyes in the ER lumen.

A push-pull method for collecting plant volatiles is described. The method allows for a comparison of volatiles induced by herbivore feeding, exogenous methyl jasmonate, and mechanical damage. This technique is also used to investigate the volatile response of undamaged branches to exposure to volatiles from herbivore-damaged branches within blueberry plants.

This article describes a method to visualize formation of an HIV-1 envelope-induced virological synapse on glass supported planar bilayers by total internal reflection fluorescence (TIRF) microscopy. The method can also be combined with immunofluorescence staining to detect activation and redistribution of signaling molecules that occur during HIV-1 envelope-induced virological synapse formation.
FAQs
These load types act through distinct physical conditions: tension stretches structures, compression reduces their dimensions, shear applies sliding forces, and fluid flow exposes cells to moving fluid. The resulting deformation can affect cell membranes, cytoskeletal networks, and extracellular matrices. Comparing these inputs helps bioengineers examine how specific mechanical environments influence cellular responses and tissue remodeling.
Load transmission involves several connected structures rather than a single sensor. Mechanical deformation can affect the cell membrane, cytoskeletal networks, and extracellular matrix, while adhesion complexes help link cellular and surrounding materials. Mechanosensitive ion channels and downstream signaling pathways then provide routes from physical deformation to biochemical activity, including changes in gene expression.
Mechanosensitive ion channels provide one route by which membrane deformation can initiate biochemical responses. When physical loading changes the membrane environment, these channels can participate in activating signaling pathways that influence gene expression and cell behavior. Their role is especially relevant when bioengineers design systems intended to reproduce mechanical conditions experienced by cells in living tissues.
Researchers can investigate the process by combining cells or tissues with biomaterials, engineered tissue constructs, or mechanical stimulation systems that reproduce physiological conditions. The selected system can expose the biological material to relevant forms of loading, after which changes in cell behavior or tissue remodeling can be examined. This approach connects mechanical environments with biological outcomes in controlled bioengineering studies.
These studies can show whether a biomaterial presents mechanical conditions that support desirable cellular responses. Because loading can influence cell growth, differentiation, migration, and tissue remodeling, researchers can use those outcomes to refine material environments and engineered constructs. The goal is to make bioengineered systems better reproduce physiological conditions and support functional tissue development.
Mechanical signaling provides a way to incorporate physical conditions into regenerative medicine and disease-modeling platforms. Engineered tissues and stimulation systems can be designed to reproduce relevant physiological environments, allowing researchers to examine how cells respond through changes in growth, differentiation, migration, or remodeling. The same bioengineering context also supports therapeutic development by connecting mechanical conditions with cell behavior.
