The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood ...

To function normally, nearly every cell in the human body relies on G-protein coupled receptors (GPCRs) to receive and send ...

Researchers at Texas A&M Health and collaborators have developed engineered CRAC channel inhibitory binders that can ...

Bone and skeletal muscle are essential components of musculoskeletal system, enabling movement, load-bearing, and systemic homeostasis. These tissues communicate through dynamic bone-muscle crosstalk ...

New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...

Activation of cell surface receptors by extracellular ligands is the hallmark of cell–cell communication and controls most physiological functions in humans. GPCRs are the largest class of such ...

BPC-157 and TB-500, originating from gastric and thymic sources respectively, both influence angiogenesis, cytoskeletal ...

One of the most important mechanisms is receptor-mediated signaling. A peptide attaches to a specific receptor on the cell surface, which then activates intracellular proteins such as kinases or ...

New simulator and computational tools generate realistic ‘virtual tissues’ and map cell-to-cell ‘conversations’ from spatial transcriptomics data, potentially accelerating AI-driven discoveries in ...

Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate ...

A 3D rendering showing the internal structure of an animal cell, with several round or wavy structures inside a border. It turns out that the redox state of a cell, such as the animal cell shown, is ...
