  • Therefore, an in-depth understanding of γδ T cells that play conflicting roles in the tumor microenvironment is necessary. (explorationpub.com)
  • According to current challenges, there is a need to explore innovative immunotherapies, maximize the tumor-killing efficacy of γδ T cells, and attenuate or eliminate tumor immunosuppression. (explorationpub.com)
  • Urticaria is not a single disease but a reaction pattern that represents cutaneous mast cell degranulation, with the condition being defined as chronic if lesions recur for longer than 6 weeks. (medscape.com)
  • The close association between mast cells and nerves in peripheral tissues, and the fact that large amounts of tryptase are released upon mast cell degranulation, makes tryptase an ideal candidate to activate PAR-2 on peripheral neurons. (asahq.org)
  • Fig. 7: Radiation-primed neutrophils boost lung metastasis via their degranulation activity. (nature.com)
  • Using intravenous injection of B16F10 melanoma cell line and EO711 triple negative breast cancer cell line, metastasis evaluation was performed. (bmj.com)
  • The chemokine signal is transduced by chemokine receptors (G-protein coupled receptors) expressed on the immune cells. (genome.jp)
  • Phosphoinositide 3-kinase (PI3K) as a key regulator of lipid signal has been reported to be involved in autophagy. (frontiersin.org)
  • We aimed to determine whether there is a functional linkage between AhR signaling and sphingolipid metabolism. (tmu.edu.tw)
  • Using tracheal epithelial cell cultures, we show that enhanced mucin production to MMF occurs in the absence of SP-A and is not dependent upon neutrophil recruitment. (bio5.org)
  • The wound begins re-epithelialization as early as day two when epithelial cells begin to migrate beneath the superficial layer of polymorphonuclear cells (the polyband), which forms beneath the blood clot. (dentistryiq.com)
  • Epithelial cells migrate at a rate of 0.5 mm to 1.0 mm per day toward the center of the wound. (dentistryiq.com)
  • Once re-epithelialization is complete, the components of basal lamina are deposited in a sequential manner starting from the wound margin, and the epithelial cells revert to their normal phenotype. (dentistryiq.com)
  • The migration of epithelial cells through the clot and provisional matrix requires the formation of a pathway through these obstacles. (dentistryiq.com)
  • Dendritic cells in the skin act as sentinel APCs, taking up antigen, then traveling to local lymph nodes where they can activate T cells. (msdmanuals.com)
  • Assembles into signaling complexes with activated receptors at the plasma membrane via interaction between its SH2 domains and the receptor tyrosine-phosphorylated ITAM domains. (icr.ac.uk)
  • they have receptors for the crystallizable fragment (Fc) region of immunoglobulin (Ig) G and for complement, which enable them to bind with immune complexes and present the complex to B cells in germinal centers of secondary lymphoid organs. (msdmanuals.com)
  • Upon stimulation by fungal proteins, CLEC7A together with SYK activates immune cells inducing the production of ROS. (icr.ac.uk)
  • Pluripotent stem cells are found in the bone marrow and can give rise to different blood cell lineages including mast cells. (proprofs.com)
  • Further, activated Socs7 -/- bone marrow derived mast cells have increased IL-7Rα transcript, which is part of the heterodimeric receptor for TSLP. (johnshopkins.edu)
  • There is compelling clinical and experimental evidence to suggest that natural killer (NK) cells play a critical role in the recognition and eradication of tumors. (frontiersin.org)
  • An important class of innate immune cells that play a critical role in mediating the antitumor immune response is the natural killer (NK) cell. (frontiersin.org)
  • We propose that collagen fibers play an important role in acupuncture-induced analgesia, and they participate in signal transmission and transform processes. (qigonginstitute.org)
  • The defining functional feature of NK cells remains their intrinsic ability to conduct "natural killing" of cellular targets without prior sensitization. (frontiersin.org)
  • SA- and HA-CD22 CAR T cells were evaluated in vitro and in vivo against clones of the pre-B ALL cell line, NALM6, which express CD22 at wild type levels (CD22 WT ), sub-physiologic levels (CD22 Lo ), supra-physiologic levels (CD22 Hi ) or in which CD22 was deleted (CD22 Neg ). (confex.com)
  • Glutathione has been proposed to act as a P2X7 receptor agonist when present at milimolar levels, inducing calcium transients and GABA release from retinal cells. (wikipedia.org)
