  • Correction: Changes in the tumor oxygenation but not in the tumor volume and tumor vascularization reflect early response of breast cancer to neoadjuvant chemotherapy. (medscape.com)
  • The role of let-7 has been demonstrated in regulating the timing of neuromuscular junction formation in the abdomen and cell-cycle in the wing. (wikipedia.org)
  • Taken together, those findings suggest that mTORC1 and mTORC2 signaling occupy a critical role in IFN-g production of ILC3s in vitro and in vivo and thus represent central regulators of protective versus inflammatory responses in the intestine. (unibas.ch)
  • While genetic and environmental factors contribute to the pathogenic process of AIH [ 2 ], dysfunctional immune responses are also crucial for the development and progression of AIH [ 3 ]. (hindawi.com)
  • Study of the inflammatory process following encounter with agents that stimulate the innate immune responses such as adjuvants opens a new horizon for the discovery of therapeutic agents including those derived from microorganisms. (uwo.ca)
  • We are now generating genetic models in which to test the the biologic relevance of these ligases in protective immune responses. (upenn.edu)
  • Here we comprehensively characterized the kinetics of cell-mediated and humoral immune responses in VRP-vaccinated mice, and demonstrate that they predominantly target the nucleoprotein (NP). (cdc.gov)
