Generation of CCR4/CD7 Bispecific CAR‐T Cells Resistant to Fratricide and Exhaustion

Advanced Science, EarlyView.
The applications of CAR T‐cell therapy in T‐cell malignancies face limitations such as fratricide, effector‐cell exhaustion, and antigen‐escape. Herein, we developed fratricide‐ and exhaustion‐resistant CAR‐T cells that targeted CCR4 and CD7 simultaneously, with optional EGFRt safety switch. Additionally, scRNA‐seq unveiled new molecular targets, which

Minor Antigen Disparities Impede Induction of Long Lasting Chimerism and Tolerance through Bone Marrow Transplantation with Costimulation Blockade

Journal of Immunology Research, 2016
Mixed chimerism and tolerance can be successfully induced in rodents through allogeneic bone marrow transplantation (BMT) with costimulation blockade (CB), but varying success rates have been reported with distinct models and protocols.

Tolerogenic effect of noninherited maternal antigens in hematopoietic stem cell transplantation

Frontiers in Immunology, 2012
Major histocompatibility complex antigens that provoke severe transplant reactions are referred to as the human leukocyte antigen (HLA) in human and as the H-2 in mice.

Leveraging Artificial Intelligence and Large Language Models for Cancer Immunotherapy

Advanced Science, EarlyView.
Cancer immunotherapy faces challenges in predicting treatment responses and understanding resistance mechanisms. Artificial intelligence (AI) and machine learning (ML) offer powerful solutions for cancer immunotherapy in patient stratification, biomarker discovery, treatment strategy optimization, and foundation model development.

In Search of Immunodominant Minor Histocompatibility Antigens [PDF]

Biology of Blood and Marrow Transplantation, 2013
survival. Larger retrospective studies should parse out relapse risk in specific cytogenetic subgroups, to offer more guidance to the practicing clinician. Our hope is that this and other retrospective studies of MRD monitoring leads to an assessment of the prognostic impact of MRD in well-defined molecular and cytogenetic subsets of AML.

Toward a network model of MHC class II-restricted antigen processing

Frontiers in Immunology, 2013
The standard model of Major Histocompatibility Complex class II (MHCII)-restricted antigen processing depicts a straightforward, linear pathway: Internalized antigens are converted into peptides that load in a chaperone dependent manner onto nascent ...

TCR-Like CAR-T Cells Targeting MHC-Bound Minor Histocompatibility Antigens

Frontiers in Immunology, 2020
Minor histocompatibility antigens (mHAgs) in allogeneic hematopoietic stem cell transplantation are highly immunogenic as they are foreign antigens and cause polymorphism between donors and recipients. Adoptive cell therapy with mHAg-specific T cells may

Evaluation of immunosuppression protocols for MHC-matched allogeneic iPS cell-based transplantation using a mouse skin transplantation model

Inflammation and Regeneration, 2022
Background Off-the-shelf major histocompatibility complex (MHC)-matched iPS cells (iPSC) can potentially initiate host immune responses because of the existence of numerous minor antigens.

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

A single nucleotide polymorphism in the Emp3 gene defines the H4 minor histocompatibility antigen.

, 2003
Minor histocompatibility antigens (minor H antigen) elicit strong T-cell-mediated responses during both graft rejection and graft versus leukemia (GvL) among MHC-matched individuals (where MHC is major histocompatibility complex). Employing expression-
