Novel approaches for immune reconstitution and adaptive immune modeling with human pluripotent stem cells

BMC Medicine, 2011
Pluripotent stem cells have the capacity to generate all cell lineages, and substantial progress has been made in realizing this potential. One fascinating but as yet unrealized possibility is the differentiation of pluripotent stem cells into thymic ...

Effects of exosomes of paratumoral thymus epithelial cells on Treg cell function in patients with thymoma-associated myasthenia gravis

Guangxi Yike Daxue xuebao
Objective To investigate the effects of exosomes derived from paratumoral thymic epithelial cells on the expression of forkhead box protein P3 (FOXP3) and the secretion of transforming growth factor-beta1 (TGF-β1) and interleukin (IL)-10 by regulatory T ...

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

Towards understanding the signalling requirements of thymic epithelial progenitor cells [PDF]

, 2018
Thymic epithelial cells (TECs) are indispensable for the development of T cells in the thymus. Two subtypes of TECs exist in the thymus, medullary mTECs and cortical cTECs.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

A simple model system enabling human CD34+ cells to undertake differentiation towards T cells [PDF]

, 2013
Channelling the development of haematopoietic progenitor cells into T lymphocytes is dependent upon a series of extrinsic prompts whose temporal and spatial sequence is critical for a productive outcome.

A Novel IDO1/NE Dual Inhibitor, IMM‐H018 Prevents the Primary and Secondary Sepsis and Ameliorates the Kidney Injury Through Inhibiting the Cytokine Storm and Microthrombosis, and Reversing Immunosuppression

Advanced Science, EarlyView.
IMM‐H018, a dual IDO1/NE inhibitor, demonstrates potent therapeutic efficacy in sepsis by simultaneously targeting excessive inflammation and immune dysfunction. It prevents both primary and secondary sepsis through anti‐inflammatory, immune‐restoring, and renoprotective mechanisms, reducing organ damage, improving immune homeostasis, preserving kidney

Role of regulatory T cells in immune tolerance [PDF]

, 2009
In this present work, we investigated the role of dendritic cells (DC) and regulatory T cells (Treg) in immune tolerance as well as their potential in the treatment of autoimmune or graft versus host (GvH) diseases.

Identification and Characterization of Thymic Epithelial Progenitor Cells [PDF]

Immunity, 2002
T cell differentiation and repertoire selection depend critically on several distinct thymic epithelial cell types, whose lineage relationships are unclear. We have investigated these relationships via functional analysis of the epithelial populations within the thymic primordium.
