Analysis of host responses to Mycobacterium tuberculosis antigens in a multi-site study of subjects with different TB and HIV infection states in sub-Saharan Africa. [PDF]

open access: yes, 2013
BACKGROUND: Tuberculosis (TB) remains a global health threat with 9 million new cases and 1.4 million deaths per year. In order to develop a protective vaccine, we need to define the antigens expressed by Mycobacterium tuberculosis (Mtb), which are ...

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

open access: yesAdvanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Flow cytometric characterization of CD34+ hematopoietic progenitor cells in mobilized peripheral blood and bone marrow of cancer patients

open access: yesHaematologica, 1996
BACKGROUND. Hematopoietic progenitor cells (HPC), identified by expression of the CD34 surface antigen, show morphological and phenotypic heterogeneity in bone marrow (BM) and peripheral blood (PB). METHODS.

Diagnostic value of immunohistochemistry staining of Bcl-2, CD34, CD20 and CD3 for distinction between discoid lupus erythematosus and lichen planus in the skin

open access: yesIndian Journal of Pathology and Microbiology, 2017
Background: Cluster of differentiation (CD) markers is a classification system for monoclonal antibodies against cell surface molecules on leukocytes and antigens from other cells. Aims: The aim of this study is to evaluate immunohistochemical markers in

Modulation of the Bovine Delayed-Type Hypersensitivity Responses to Defined Mycobacterial Antigens by a Synthetic Bacterial Lipopeptide [PDF]

open access: yes, 2003
The use of defined protein and peptide antigens can overcome specificity limitations of purified protein derivatives in the detection of bovine tuberculosis when the antigens are used in blood-based tests. Since the use of these specific antigens as skin

Matrix Stiffness Orchestrates Mesenchymal Stem Cell Lineage Commitment Toward Osteogenesis and Adipogenesis Through the PIEZO1/SP1/STC2 Axis

open access: yesAdvanced Science, EarlyView.
Matrix stiffness directs mesenchymal stem cell lineage commitment through PIEZO1‐dependent activation of the SP1/STC2 pathway. Stiff matrices favor osteogenesis and suppress adipogenesis, whereas the loss of PIEZO1 function impairs early bone formation. STC2 retains lineage‐regulatory activity even when PIEZO1 is inactive.

Leveraging Microphysiological Systems to Facilitate Neutrophil‐Based Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Microphysiological systems are emerging as powerful human‐relevant platforms for studying neutrophil biology in cancer. Current applications of spheroids, organoids, and organ‐on‐a‐chip models are reviewed, together with future opportunities in behaviorome profiling, multi‐omics integration, personalized medicine, immune crosstalk, and multi‐organ ...

Hepatic arterial infusion of autologous CD34+ cells for hepatitis C virus-related decompensated cirrhosis: A multicenter, open-label, exploratory randomized controlled trial

open access: yesRegenerative Therapy
Introduction: In this multicenter clinical study, we aimed to investigate the efficacy and safety of the transhepatic arterial administration of granulocyte-colony stimulating factor (G–CSF)–mobilized autologous peripheral blood (PB)-CD34+ cells compared

Mutant KRAS‐m6A Epitranscriptome Axis Promotes Colorectal Cancer and is a Therapeutic Target

open access: yesAdvanced Science, EarlyView.
Mutant KRAS‐m6A axis promotes colorectal cancer (CRC) progression. Mutant KRAS stabilizes METTL3, leading to increased m6A‐modified BCL9L mRNA and translation of BCL9L protein. BCL9L in turn mediates TGF‐β secretion to induce differentiation of Treg and an immunosuppressive microenvironment.

RHAMM/HMMR (CD168) is not an ideal target antigen for immunotherapy of acute myeloid leukemia

open access: yesHaematologica, 2012
Background Criteria for good candidate antigens for immunotherapy of acute myeloid leukemia are high expression on leukemic stem cells in the majority of patients with acute myeloid leukemia and low or no expression in vital tissues.
