  • Both the spike protein and ACE2 are then cleaved, allowing genetic material from the virus to enter the host cell. (eurekalert.org)
  • The massive machine runs atomic-level simulations of a key coronavirus protein, looking for hidden vulnerabilities to guide development of antiviral drugs. (forbes.com)
  • The coronavirus is covered with so-called "spike proteins," which are actually three proteins joined together. (forbes.com)
  • Covid-19 coronavirus binding to receptors on the cell surface. (forbes.com)
  • This year, with the coronavirus pandemic boosting people's interest in protein research, participation soared to more than a million machines. (forbes.com)
  • In a mouse experimental arthritis model, NKT17 cells are increased as the disease progresses, while NKT1 numbers negatively correlates with disease severity, with this protective effect of NKT1 linked to their IFN-γ expression. (nih.gov)
  • The expression of biomarkers can be detected intracellularly or on the cell membrane of melanoma cells or noncancer cells in association with the melanoma. (hindawi.com)
  • Therefore, 17beta-estradiol increased expression of alpha(2C)-ARs by interacting with cell surface receptors to cause a cAMP/Rap2-dependent increase in alpha(2C)-AR transcription. (cdc.gov)
  • This protein is capable of binding to the Fc portion of immunoglobulins, especially IgGs, from a large number of species. (sigmaaldrich.com)
  • In species that are not biologically wired to be monogamous, such as mountain voles and common mice, the nucleus accumbens doesn't have oxytocin receptors. (psychologytoday.com)
  • Tetracycline inhibits bacterial protein synthesis by binding with 30S and, possibly, 50S ribosomal subunit(s). (medscape.com)
  • Some drugs need to attach to proteins on the surface of cells called receptors in order to work properly. (cdc.gov)
  • Some drugs need to be actively taken into the tissues and cells in which they act. (cdc.gov)
  • Your DNA can also affect how quickly some drugs are removed from the cells in which they act. (cdc.gov)
  • If drugs are removed from the cell too quickly, they might not have time to act. (cdc.gov)
  • Anti-cancer drugs used in combination with surgery and/or radiation to destroy residual cancer cells to prevent or delay recurrence. (ucsfhealth.org)
