摘要:
Provided are methods of treatment, such as methods involving administering and/or determining dosing of, cell therapy, such as of cells engineered with a recombinant receptor, such as a T cell receptor (TCR) or chimeric antigen receptor (CAR). In some embodiments, the methods include determining a therapeutic range and/or window for dosing, for example, based on the estimated probabilities of risk of developing a toxicity and estimated probabilities of a treatment outcome or response, such as treatment, reduction nor amelioration of a sign or symptom thereof, or degree or durability thereof, following administration of the cell therapy or engineered cells. In some aspects, the methods involve administering an agent capable of modulating the engineered cells. Also provided are methods of ameliorating and/or treating a toxicity.
摘要:
Provided are immunomodulatory pharmaceutical and non-pharmaceutical compositions that include alpha-synuclein and at least one preselected antigen, such as at least one preselected peptide antigen or immunogen. Also provided are methods for modulating immune activity toward at least one preselected antigen in an at least substantially antigen-specific manner that include administering such a composition to a human patient or to a non-human mammalian subject. Still further provided are enhanced assay methods for quantifying antigen-specific cellular responses, such as cytokine release, to preselected antigens.
摘要:
A method for diagnosing or treating a mammalian subject having, or at risk of developing cancer, comprising: generating a circulating anti-cancer CD4 + Th1response from antigen presenting cells or their precursors and CD4 + T-cells from a sample of said subject's blood which causes secretion of interferon-gamma ("IFN-γ"); and detecting said anti-cancer CD4 + Th1 response to determine if said response is depressed. A method for restoring HER2-specific CD4 + Th1immune response in a HER2 -positive breast cancer patient in need thereof, comprising: administering to said patient a therapeutically effective amount of a dendritic cell ("DC") vaccine comprising autologous DCs pulsed with HER2 -derived MHC class II binding peptides ("DC vaccination") to elevate said patient's anti-HER2 CD4 + Th1 response; and measuring said anti-HER2 Th1 response of said patient pre- and post-DC vaccination to determine the amount of increase in said response.
摘要:
Disclosed herein is a method of detecting antigen specific T cells in a sample isolated from a subject and mapping immunostimulatory epitopes of the antigen. Such methods may be used in methods of making antigen specific T cell compositions, e.g., for the treatment of diseases such as cancer, infectious diseases and autoimmune disorders.
摘要:
A method of diagnosing an inflammatory condition of the genital tract caused by bacterial vaginosis (BV) or a sexually transmitted infection (STI) in a female subject is described. The method measures the concentration of IP-10 and either of IL- β or IL- α in a sample of cervicovaginal fluid from the subject and compares these to predetermined levels of IP-10 and either of IL-1β or IL-1α, respectively. A down- regulated IP-10 level in the sample or an up-regulated IL-1β or IL-1α level in the sample will be regarded as a positive result, i.e. indicating that there is a high probability that the subject has an STI or BV. The subject could then either be directly treated, e.g. with broad spectrum antibiotics, or referred for appropriate STI screening. The sample can be obtained from a vaginal secretion from the subject. A test kit for performing the method is also described.
摘要:
The present invention provides compositions and methods for detection schemes for ascertaining pregnancy status of an animal. The compositions and methods employ interferon-tau (IFNT) and/or antibodies specific for IFNT. Methods of the present invention detect the presence of IFNT in samples obtained from animals as an early indicator of pregnancy. Methods are provided to identify non-pregnant animals so that management decisions regarding rebreeding can be made earlier compared to existing approaches.
摘要:
A method of characterizing sepsis in a subject involves determining an amount in a biological sample from the subject of each biomarker in a biomarker panel including at least two biomarkers; and calculating a risk index or sepsis probability score using the amounts of biomarkers in the biomarker panel. Exemplary biomarker panels include TNF-alpha, interleukin-6, interleukin-10, lipopolysaccharide binding protein, and C-reactive protein; IL-1beta, procalcitonin, absolute neutrophil count, and immature granulocyte count; and Interleukin-8, GM-CSF, MCP1, and INF-gamma. The method can further involve determining one or more clinical parameters about the subject, and calculating the risk index using the amounts of the biomarkers in the biomarker panel and the clinical parameters.
