  • As of data cut-off on June 10, 2023, in patients that received the highest doses of NKX101 (3 weekly doses at 1 billion or 1.5 billion cells per dose) after fludarabine/cyclophosphamide (Flu/Cy) LD, 4 of 18 achieved CR/CRi (22% CR/CRi rate) and 3 of 18 achieved a complete response with hematologic recovery CR (17% CR rate).

  • The update is expected to include additional patients treated with NKX101 at 1.5 billion cells/dose x 3 dose regimen following Flu/Ara-C LD, as well as longer-term follow up of patients who were in response as of the June 2023 data cut-off. (tmcnet.com)
  • We developed a statistical framework for associating receptors to disease from only a small cohort of patients, with no need for a control cohort. (elifesciences.org)
  • Patients with CLL have a higher-than-normal white blood cell count, which is determined by complete blood count (CBC). (medscape.com)
  • The cells of origin in most patients with CLL are clonal B cells arrested in the B-cell differentiation pathway, intermediate between pre-B cells and mature B cells. (medscape.com)
  • L'étude portait sur 20 patients atteints d'un carcinome gastrique, 20 patients souffrant d'une gastrite à H. pylori et 20 personnes en tant que groupe témoin. (who.int)
  • Various biological processes including immunoreaction of infection, tumor prevention, and human aging could cause telomere damage, tumor-related stress responses, and T regulatory (Treg) cells activation, which even trigger T cell senescence showing the distinctive phenotypic and functional alternation [ 9 , 10 ].

  • The detection sensitivity offered by the luminescent signal, along with the improved delivery provided by the gold scaffold, offer opportunities for monitoring biological responses upon selectively targeting cancer cells in in vivo models. (bham.ac.uk)
  • The release of tumor-associated antigens and induction of immunogenic cell death consequently stimulate anti-tumor immune responses with potential for long-lasting tumor control (9). (columbiagypsy.net)
  • It is found in large quantities in glioblastoma cells, but is virtually undetectable in healthy brain tissue. (dkfz.de)
