Is There any Greater Possibility in Finding HLA-identical Unrelated Hematopoietic Stem Cell Donors among Thalassemia Families for Transplantation of Thalassemia Patients? [PDF]

International Journal of Hematology-Oncology and Stem Cell Research, 2004
Background: Thalassemia is probably the most common single gene disorder causing a major public health problem in the world. Currently, allogenic hematopoietic stem cell transplantation (HSCT) is the only curative therapy for thalassemia.

A lentiviral vector encoding fusion of light invariant chain and mycobacterial antigens induces protective CD4+ T cell immunity

Cell Reports, 2022
Summary: Lentiviral vectors (LVs) are highly efficient at inducing CD8+ T cell responses. However, LV-encoded antigens are processed inside the cytosol of antigen-presenting cells, which does not directly communicate with the endosomal major ...

Antigen Presentation in the Gut

Canadian Journal of Gastroenterology, 1990
The induction of T cell responses requires recognition of antigens in association with class II major histocompatibility complex (MHC) proteins and specialized antigen-presenting cells.

Resting Porcine T Lymphocytes Expressing Class II Major Histocompatibility Antigen

Immunobiology, 1991
The immune system of swine is unique in that the expression of CD4 and CD8 antigens defines four subpopulations of resting, extrathymic (CD1-) T lymphocytes in the circulation as well as in lymphoid tissue. Here it is documented that the specialty of the porcine T lymphocyte compartment extends to the expression of class II MHC (SLA) antigens.

The Phosphoinositide Kinase PIKfyve Promotes Cathepsin-S-Mediated Major Histocompatibility Complex Class II Antigen Presentation

iScience, 2019
Summary: Antigen presentation to T cells in major histocompatibility complex class II (MHC class II) requires the conversion of early endo/phagosomes into lysosomes by a process called maturation.

The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

Aging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

Regulation of major histocompatibility complex class II gene expression in trophoblast cells

Reproductive Biology and Endocrinology, 2004
Trophoblast cells are unique because they are one of the few mammalian cell types that do not express major histocompatibility complex (MHC) class II antigens, either constitutively or after exposure to IFN-γ.

CD1-mediated immune responses in mucosal tissues: molecular mechanisms underlying lipid antigen presentation system

Experimental and Molecular Medicine, 2023
The cluster of differentiation 1 (CD1) molecule differs from major histocompatibility complex class I and II because it presents glycolipid/lipid antigens. Moreover, the CD1-restricted T cells that recognize these self and foreign antigens participate in

AUTOIMMUNE THYROIDDISEASE AND THYROID CELL CLASS II MAJOR HISTOCOMPATIBILITY COMPLEX ANTIGENS [PDF]

Clinical Endocrinology, 1987
Differences in the immune response to antigenic stimuli, including thyroid autoantigens, have been linked to a group of genes known collectively as the Major Histocompatibility Complex (MHC), which in humans is referred to as the Human Leukocyte Antigen (HLA) complex (Benacerraf, 1981). These genes encode a series of polymorphic cell surface molecules;

Systemic T Cell Receptor Profiling Reveals Adaptive Immune Activation and Potential Immune Signatures of Diagnosis and Brain Atrophy in Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Epilepsy is increasingly associated with immune dysregulation and inflammation. The T cell receptor (TCR), a key mediator of adaptive immunity, shows repertoire alterations in various immune‐mediated diseases. The unique TCR sequence serves as a molecular barcode for T cells, and clonal expansion accompanied by reduced overall TCR ...
