Effects of an immunosuppressive active component of Periplocae Cortex (Periploca sepium Bge.) on positive selection of thymocytes in vitro

open access: yesJournal of Traditional Chinese Medical Sciences, 2018
Objective: To determine the effect of an immunosuppressive active component (periploside A) isolated from the stem bark of Periplocae Cortex (Periploca sepium Bge.), a Chinese medicinal herb used in the treatment of rheumatoid arthritis for centuries in ...

The sensitivity of cells with the various level of NAD(P)H:quinone oxidoreductase 1 to cytotoxic action of quinonimines and α-тоcopherol synthetic derivatives [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2015
The effects of α-tocopherol with shortened to 6 carbon atoms side chain (α-Toc-C6), α-tocopherol succinate (α-TS) and quinonimine 2,6-dichlorophenolindophenol (DCPIP) on DT-diaphorase activity and viability of rat thymocytes, splenocytes and hepatocytes ...

Proteasome activities decrease during dexamethasone-induced apoptosis of thymocytes [PDF]

open access: yes, 1998
The induction of apoptosis in thymocytes by the glucocorticoid dexamethasone was used as a model system to investigate whether there are changes in 20 S and 26 S proteasome activities during apoptosis.

Aire-dependent production of XCL1 mediates medullary accumulation of thymic dendritic cells and contributes to regulatory T cell development [PDF]

open access: yes, 2011
Dendritic cells (DCs) in the thymus (tDCs) are predominantly accumulated in the medulla and contribute to the establishment of self-tolerance. However, how the medullary accumulation of tDCs is regulated and involved in self-tolerance is unclear. We show

Endoplasmic Reticulum Stress and Unfolded Protein Response in Atm-Deficient Thymocytes and Thymic Lymphoma Cells Are Attributable to Oxidative Stress

open access: yesNeoplasia: An International Journal for Oncology Research, 2008
Both oxidative stress and endoplasmic reticulum (ER) stress have been implicated in carcinogenesis. It is well documented that cells deficient in the ataxia-telangiectasia mutated (ATM) gene undergo oxidative stress, which is critically involved in ...

Calcium Signaling Is Impaired in PTEN-Deficient T Cell Acute Lymphoblastic Leukemia

open access: yesFrontiers in Immunology, 2022
PTEN (Phosphatase and TENsin homolog) is a well-known tumor suppressor involved in numerous types of cancer, including T-cell acute lymphoblastic leukemia (T-ALL). In human, loss-of-function mutations of PTEN are correlated to mature T-ALL expressing a T-

Expression of genes encoding cytotoxic cell-associated serine proteases in thymocytes [PDF]

open access: yes, 1990
A family of homologous serine esterases designated granzyme A-H and the pore-forming protein perforin are present in cytoplasmic granules of mature peripheral cytolytic T lymphocytes and natural killer cells.

HDAC3 restrains CD8-lineage genes to maintain a bi-potential state in CD4+CD8+ thymocytes for CD4-lineage commitment

open access: yeseLife, 2019
CD4 and CD8 T cells are vital components of the immune system. We found that histone deacetylase 3 (HDAC3) is critical for the development of CD4 T cells, as HDAC3-deficient DP thymocytes generate only CD8SP thymocytes in mice.

A novel activity on thymocytes cells exerted by the rattlesnake (Crotalus durissus cumanensis) venom

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2021
Introduction: The thymus is active mainly during the neonatal and pre-adolescent periods. Objective: To test naïve thymocytes proliferation and monocytes stimulation. Materials and methods: We collected fresh thymus tissue from neonate mice after surgery.
