Automated microscopic cell analysis

This disclosure describes single-use test cartridges, cell analyzer apparatus, and methods for automatically performing microscopic cell analysis tasks, such as counting and analyzing blood cells in biological samples. A small measured quantity of a biological sample, such as whole blood, is placed in a mixing bowl on the disposable test cartridge after being inserted into the cell analyzer. The analayzer also deposits a known amount of diluent/stain in the mixing bowl and mixes it with the blood. The analyzer takes a measured amount of the mixture and dispenses in a sample cup on the cartridge in fluid communication with an imaging chamber. The geometry of the imaging chamber is chosen to maintain the uniformity of the mixture, and to prevent cells from crowding or clumping as it is transferred into the imaging chamber by the analyzer. Images of all of the cellular components within the imaging chamber are counted and analyzed to obtain a complete blood count.

NEUTRALIZING GP41 ANTIBODIES AND THEIR USE

Monoclonal neutralizing antibodies are disclosed that specifically bind to the HIV-1 gp41 membrane-proximal external region (MPER). Also disclosed are compositions including the disclosed antibodies that specifically bind gp41, nucleic acids encoding these antibodies, expression vectors including the nucleic acids, and isolated host cells that express the nucleic acids. The antibodies and compositions disclosed herein can be used for detecting the presence of HIV-1 in a biological sample, or detecting an HIV-1 infection or diagnosing AIDS in a subject. In additional, the broad neutralization breadth of the disclosed antibodies makes them ideal for treating a subject with an HIV infection. Thus, disclosed are methods of treating and/or preventing HIV infection.

METHODS FOR PROFILING THE T CELL REPERTOIRE
20180000913 · 2018-01-04 ·

The present disclosure relates to methods for profiling subject specific and personalized T cell receptor (TCR) repertoires using a single-cell sequencing method. More particularly, disclosed are methods for determining binding of T cell receptors to subject specific neoantigens. In addition, the techniques herein may identify the antigenic targets of T cell receptors in the context of tumor neoantigens. Moreover, the present disclosure enables the discovery of T cell targets in numerous diseases, with implications for understanding the basic mechanisms of the mammalian immune response and for developing antigen-specific diagnostic markers and therapies. Finally, cloned TCRs can be used to formulate personalized immunotherapies for those inflicted with a disease, such as cancer.

The invention also relates to a kit to perform the method of the invention.

Cancer vaccine composition

A cancer vaccine composition for human leukocyte antigen (HLA)-A*0206-positive persons, comprising a protein product of the tumor suppressor gene WT1 or a partial peptide thereof.

PEPTIDES AND COMBINATION OF PEPTIDES FOR USE IN IMMUNOTHERAPY AGAINST VARIOUS TUMORS

A method of treating a patient who has hepatocellular carcinoma (HCC), colorectal carcinoma (CRC), glioblastoma (GB), gastric cancer (GC), esophageal cancer, NSCLC, pancreatic cancer (PC), renal cell carcinoma (RCC), benign prostate hyperplasia (BPH), prostate cancer (PCA), ovarian cancer (OC), melanoma, breast cancer (BRCA), CLL, Merkel cell carcinoma (MCC), SCLC, Non-Hodgkin lymphoma (NHL), AML, gallbladder cancer and cholangiocarcinoma (GBC, CCC), urinary bladder cancer (UBC), and uterine cancer (UEC) includes administering to said patient a composition containing a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide. A pharmaceutical composition contains activated T cells that selectively recognize cells in a patient that aberrantly express a peptide, and a pharmaceutically acceptable carrier, in which the T cells bind to the peptide in a complex with an MHC class I molecule, and the composition is for treating the patient who has HCC, CRC, GB, GC, esophageal cancer, NSCLC, PC, RCC, BPH, PCA, OC, melanoma, BRCA, CLL, MCC, SCLC, NHL, AML, GBC, CCC, UBC, and/or UEC. A method of treating a patient who has HCC, CRC, GB, GC, esophageal cancer, NSCLC, PC, RCC, BPH, PCA, OC, melanoma, BRCA, CLL, MCC, SCLC, NHL, AML, GBC, CCC, UBC, and/or UEC includes administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, thereby inducing a T-cell response to the HCC, CRC, GB, GC, esophageal cancer, NSCLC, PC, RCC, BPH, PCA, OC, melanoma, BRCA, CLL, MCC, SCLC, NHL, AML, GBC, CCC, UBC, and/or UEC.

METHODS FOR PREDICTING THE RISK OF RECURRENCE AND/OR DEATH OF PATIENTS SUFFERING FROM A SOLID CANCER AFTER PREOPERATIVE ADJUVANT THERAPIES
20230235408 · 2023-07-27 ·

The inventors assessed in locally advanced rectal cancer whether a diagnostic biopsy-adapted Immunoscore (ISg) could predict response to neoadjuvant treatment (nT) and better define patients eligible to an organ preservation strategy (“Watch-and-Wait”). The inventors showed that IS.sub.B was an independent parameter, more informative than pre- (P<0.001) and post-nT (P<0.05) imaging to predict disease-free survival. IS.sub.B combined with imaging post-nT discriminated very good responders that could benefit from organ preservation strategy. Accordingly, the present invention relates to methods for predicting the recurrence and/or death of patients suffering from a solid cancer after preoperative adjuvant therapies.

Described herein are compositions and methods for diagnosing late-onset Alzheimer's disease (LOAD), treating LOAD and assessing efficacy of therapeutic agents used to treat LOAD.

Dysfunctional antigen-specific CD8.SUP.+ .T cells in the tumor microenvironment

Provided herein are compositions and methods for detecting and/or targeting dysfunctional tumor antigen-specific CD8.sup.+ T cells in the tumor microenvironment for diagnostic, therapeutic and/or research applications. In particular, dysfunctional tumor antigen-specific CD8.sup.+ T cells are detected and/or targeted via their expression of cell surface receptors described herein, such as 4-1BB, LAG-3, or additional markers that correlate with 4-1BB and LAG-3 expression, such as markers differentially expressed on the surface of the T cells.
