Was ist die zelluläre Signalübertragung?
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes.…
Bakterielle Signalübertragung
At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that…
Signalwege der Hefe
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes—cells that have a nucleus. Cell signaling in yeast is similar to…
Kontaktabhängige Signalübertragung
Contact-dependent signaling uses specialized cytoplasmic channels between cells that allow the flow of small molecules between them. In animal cells,…
Autokrine Signalübertragung
Secreted signals can act on a variety of target cells. In some cases, the cell that secretes a signal also detects and responds to the signaling…
Parakrine Signalübertragung
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. The signal only triggers a…
Synaptische Signalübertragung
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be…
G-Protein-gekoppelte Rezeptoren
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that…
intrazelluläre Rezeptoren
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can…
Endokrine Signalübertragung
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the…
Was sind sekundäre Messenger?
Because many receptor binding ligands are hydrophilic, they do not cross the cell membrane and thus their message must be relayed to a second…
Intrazelluläre Signalkaskaden
Intracellular signaling cascades amplify a signal originating extracellularly and directs it to its intended intracellular target resulting in…
Ionenkanäle
Ion channels maintain the membrane potential of a cell. For most cells, especially excitable ones, the inside has a more negative charge than the…
Enzymgebundene Rezeptoren
Enzyme-linked receptors are proteins which act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of…
Screening bioaktiver Nanopartikel in phagozytischen Immunzellen für Inhibitoren der Toll-like Receptor Signaling
Pharmacological regulation of Toll-like receptor (TLR) responses holds great promise in the treatment of many inflammatory diseases. However, there…
Echtzeit-Live-Imaging von T-Zell-Signaling Complex Formation
Protection against infectious diseases is mediated by the immune system 1,2. T lymphocytes are the master coordinators of the immune system,…
Identifizierung von intrazellulärer Induzierte in lebenden Zellen durch Interaktion Signalisierung mit Benachbarte Zellen, die eine programmierten Zelltods
Cells dying by apoptosis, also referred to as regulated cell death, acquire multiple new activities that enable them to influence the function of…
