Developmental conversion of thymocyte-attracting cells into self-antigen-displaying cells in embryonic thymus medulla epithelium

open access: yeseLife
Thymus medulla epithelium establishes immune self-tolerance and comprises diverse cellular subsets. Functionally relevant medullary thymic epithelial cells (mTECs) include a self-antigen-displaying subset that exhibits genome-wide promiscuous gene ...

Three potential sources of cell injuries of lymphoid cells associated with developments of lymphoid leukemia and lymphoma [PDF]

open access: yesarXiv, 2018
Lymphoid leukemia (LL) and lymphoma are blood cancers developed from lymphoid cells (LCs). To understand the cause and the mechanism of cell transformation of a LC, we studied the potential sources of cell injuries of LCs and analyzed how DNA changes are generated and accumulate in LCs. I.

Peripheral Biomarker Signatures in Rheumatoid Arthritis–Associated Interstitial Lung Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis–associated interstitial lung disease (RA‐ILD) is a significant cause of morbidity and mortality among patients with RA, yet effective risk stratification for RA‐ILD is lacking. We sought to characterize unique peripheral blood biomarker signatures in RA that could improve RA‐ILD discrimination beyond clinical and genetic ...

Dynamics of T Cell Receptor Distributions Following Acute Thymic Atrophy and Resumption [PDF]

open access: yesarXiv, 2019
Naive human T cells are produced in the thymus, which atrophies abruptly and severely in response to physical or psychological stress. To understand how an instance of stress affects the size and "diversity" of the peripheral naive T cell pool, we derive a mean-field autonomous ODE model of T cell replenishment that allows us to track the clone ...

Systemic T‐cell and local macrophage interactions mediate granule size‐dependent biological hydroxyapatite foreign body reaction

open access: yesBMEMat, EarlyView.
This study expanded our understanding of the size effect of biological hydroxyapatite (BHA) granules from a biological perspective rather than physical defect accommodation. Besides, we proposed the multi‐level structure of commercially available BHA granules based on their microstructure and provided a biological mechanism for the classification of ...

Copy number variations analysis in a cohort of 47 fetuses and newborns with congenital diaphragmatic hernia

open access: yesPrenatal Diagnosis, Volume 42, Issue 13, Page 1627-1635, December 2022., 2022
Abstract Objectives The congenital diaphragmatic hernia (CDH), characterized by malformation of the diaphragm and lung hypoplasia, is a common and severe birth defect that affects around 1 in 4000 live births. However, the etiology of most cases of CDH remains unclear.

Nickel (II) Ions Interaction with Polynucleotides and DNA of Different GC Composition [PDF]

open access: yesarXiv, 2009
The goal of the work was to study the role of GC alternative dimmers in the binding of DNA with Ni (II) ions. The method of ultraviolet difference spectroscopy has been applied to investigate Ni (II) ions interactions with DNA extracted from Clostridium perfringens, Mice liver (C3HA line), Calf thymus, Salmon sperm, Herring sperm, E.coli, Micrococcus ...

Nonconventional Techniques in Plant Alkaloid Extraction: A Decade of Progress (2014–2023)

open access: yesChemistry &Biodiversity, EarlyView.
This figure seeks to represent the evolution of the different unconventional approaches that were adopted for the extraction of plant‐derived alkaloids during the decade from 2014 to 2023. ABSTRACT Plant metabolism encompasses primary and secondary pathways, with secondary metabolism yielding diverse natural products crucial for plant adaptation and ...
