  • Immune responses to antigens originating in the central nervous system (CNS) are generally attenuated, as collateral damage can have devastating consequences. (xstrahl.com)
  • However, extremely strong immune responses have been generated using a "boost" to the immune system, provided by viruses that encode antigens similar to the target. (oncolink.org)
  • In that time, he studied human anti-cancer immune responses pre- and post- cancer vaccination and cytokine administration to determine why anti-tumor immune responses were not more clinically effective. (cancerprogress.live)

  • Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) are the two most prominent adverse events of CAR T cell therapy. (apbmt.org)
  • In cancer vaccines, the goal is to generate an immune response to these antigens through a vaccine. (wikipedia.org)
  • The vaccine formulations targeting these antigens have caused a relatively weak immune response. (oncolink.org)
  • This results both in enhanced vaccine responses and, at times, down-regulation of other immune reactivities, such as transplant rejection and the risk of developing certain immunologic diseases, such as type I diabetes. (unu.edu)
  • Prostate acid phosphatase (PAP) is expressed in approximately 95% of prostate cancers and is mainly limited to prostate tissue, which is a target for prostate cancer tumor vaccine development. (asmepress.com)
  • Results Sixty-six patients were screened and 19 enrolled of whom 14 received at least 3 doses of the vaccine and thus evaluated for the primary immunologic endpoint. (bmj.com)
  • Radiotherapy exacerbates tumor-promoting innervation and nerve signaling in rectal cancer. (rochester.edu)
  • Combination of NKG2A and PD-1 Blockade Improves Radiotherapy Response in Radioresistant Tumors. (rochester.edu)
  • These data suggest that CNS tumors may impair systemic antitumor immunity and consequently accelerate cancer progression locally as well as outside the CNS, whereas antitumor immunity may be restored by combining vaccination with radiation therapy. (xstrahl.com)
  • Cancer vaccines use tumor cell-associated antigens to induce a specific anti-tumor immune response that is durable and robust. (asmepress.com)
  • Indeed, application of the RESTORE protocol, i.e. pre-culturing PBMCs for two days at a high cell density before initiation of antigenic stimulation, demonstrated that CD8 T-cell responses to a broad range of viral and to tumor-associated antigens are greatly underestimated, and sometimes even remain undetected if conventional, unprocessed PBMC cultures are used. (uni-wuerzburg.de)
  • The latter finding is particularly striking with regard to the appearance of Wilms tumor 1 (WT1)-specific CD8 T-cell responses in leukemia patients after allogeneic bone marrow transplantation. (uni-wuerzburg.de)
  • Taken together, the RESTORE protocol, which was initially described for the CD4 T-cell response to the antibody TGN1412 permits a more meaningful monitoring of CD8 T-cell responses to viral infections and tumors. (uni-wuerzburg.de)
  • A lot goes on in immunological diagnosis for tumors so let's dive right in. (techsling.com)
  • That just about covers immunological diagnosis in tumors although it is a rather large field. (techsling.com)
  • However, this overwhelming immunological derangement can also lead to other on-target, off-tumor immune-mediated complications. (apbmt.org)
  • Renal and skin cancers also responded to the treatment and low doses similar to diabetes prescription concentrations were still effective for tumour rejection. (labcanada.com)
  • CAR T therapies can cause immunologic adverse events and management of these toxicities could also instigate a profound immune suppression state that predisposes patients to a variety of infectious complications. (apbmt.org)
  • This Antibody was verified by Cell treatment to ensure that the antibody binds to the antigen stated. (thermofisher.com)
  • Mitogen-activated Protein Kinase pathway (RAS/MAPK) pathway activation was shown to be present in about 50% of HCC tumors. (forgetmenotinitiative.org)

  • Infusion reactions (IRs) can be broadly categorized by their immunologic mechanism. (cancernetwork.com)
  • Absence of a costimulatory signal results in T-cell anergy, which is a key mechanism of peripheral immune tolerance to self-antigen in normal immunoregulation. (mhmedical.com)
