세포 신호전달이란 무엇인가?
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes.…
박테리아 신호
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…
효모 신호
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes—cells that have a nucleus. Cell signaling in yeast is similar to…
접촉 의존 신호전달
Contact-dependent signaling uses specialized cytoplasmic channels between cells that allow the flow of small molecules between them. In animal cells,…
자가분비 신호전달
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…
측분비 신호전달
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. The signal only triggers a…
시냅스 신호전달
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-단백질 결합 수용체
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that…
내부 수용체
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can…
내분비 신호전달
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the…
2차 전달자란 무엇인가?
Because many receptor binding ligands are hydrophilic, they do not cross the cell membrane and thus their message must be relayed to a second…
세포 내 신호전달 연쇄반응
Intracellular signaling cascades amplify a signal originating extracellularly and directs it to its intended intracellular target resulting in…
이온 채널
Ion channels maintain the membrane potential of a cell. For most cells, especially excitable ones, the inside has a more negative charge than the…
효소 결합 수용체
Enzyme-linked receptors are proteins which act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of…
Toll-like Receptor Signaling의 억제제에 대한 식세포 면역 세포에서의 생체 활성 나노 입자의 스크리닝
Pharmacological regulation of Toll-like receptor (TLR) responses holds great promise in the treatment of many inflammatory diseases. However, there…
T 세포의 실시간 라이브 영상은 복잡한 형성을 신호
Protection against infectious diseases is mediated by the immune system 1,2. T lymphocytes are the master coordinators of the immune system,…
세포 내 이웃 셀을받은 사멸 세포 죽음과의 상호 작용에 의해 실행 가능한 세포에서 유도 된 이벤트를 시그널링의 식별
Cells dying by apoptosis, also referred to as regulated cell death, acquire multiple new activities that enable them to influence the function of…
