  2. Tubuloglomerular feedback - Wikipedia

    en.wikipedia.org/wiki/Tubuloglomerular_feedback

    A high protein diet affects the feedback activity by making the single nephron glomerular filtration rate higher, and the Na and Cl concentrations in early distal tubule fluid lower. The signal eliciting the TG feedback response is affected. The increased load on the kidney of high-protein diet is a result of an increase in reabsorption of NaCl ...

  3. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways [115] The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as ...

  4. Downregulation and upregulation - Wikipedia

    en.wikipedia.org/wiki/Downregulation_and_up...

    The disequilibrium caused by these changes often causes withdrawal when the long-term use of a drug is discontinued. Upregulation and downregulation can also happen as a response to toxins or hormones. An example of upregulation in pregnancy is hormones that cause cells in the uterus to become more sensitive to oxytocin.

  5. Purinergic signalling - Wikipedia

    en.wikipedia.org/wiki/Purinergic_signalling

    Purinergic signalling (or signaling: see American and British English differences) is a form of extracellular signalling mediated by purine nucleotides and nucleosides such as adenosine and ATP. It involves the activation of purinergic receptors in the cell and/or in nearby cells, thereby regulating cellular functions.

  6. NF-κB - Wikipedia

    en.wikipedia.org/wiki/NF-κB

    Osteoprotegerin (OPG), which is a decoy receptor homolog for RANK ligand , inhibits RANK by binding to RANKL, and, thus, osteoprotegerin is tightly involved in regulating NF-κB activation. [ 28 ] Many bacterial products and stimulation of a wide variety of cell-surface receptors lead to NF-κB activation and fairly rapid changes in gene ...

  7. RANK - Wikipedia

    en.wikipedia.org/wiki/RANK

    RANK is the receptor for RANK-Ligand and part of the RANK/RANKL/OPG signaling pathway that regulates osteoclast differentiation and activation. It is associated with bone remodeling and repair, immune cell function, lymph node development, thermal regulation, and mammary gland development.

  8. Cyclic adenosine monophosphate - Wikipedia

    en.wikipedia.org/wiki/Cyclic_adenosine_monophosphate

    cAMP represented in three ways Adenosine triphosphate. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3',5'-cyclic adenosine monophosphate) is a second messenger, or cellular signal occurring within cells, that is important in many biological processes. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms ...

  9. Interleukin 8 - Wikipedia

    en.wikipedia.org/wiki/Interleukin_8

    IL-8 is the primary cytokine involved in the recruitment of neutrophils to the site of damage or infection; in a process called chemotaxis.A number of variables are essential for the successful chemotaxis of neutrophils, including the increased expression of high affinity adhesion molecules to secure the neutrophil to the endothelium near the affected site (and is therefore not washed away ...
