Zaiken M, Jin S, McDonald-Hyman C, Hartigan C, Sage P, Hippen K, et al.
Blood . 2025 Feb; PMID: 39899881
Chronic graft-versus-host disease (cGVHD) is the leading cause of morbidity and non-relapse associated mortality following allogeneic hematopoietic cell transplantation (aHSCT). Treating steroid resistant/refractory cGVHD remains challenging. Epigenetic regulators can have...

Gioulbasani M, Aijo T, Liu S, Montgomery S, Montgomery N, Corcoran D, et al.
Commun Biol . 2024 Dec; 7(1):1606. PMID: 39627458
Ten eleven translocation (TET) proteins are tumor suppressors that through their catalytic activity oxidize 5-methylcytosine to 5-hydroxymethylcytosine, to promote DNA demethylation and to regulate gene expression. Notably, TET2 is one...

Gioulbasani M, Aijo T, Valenzuela J, Bettes J, Tsagaratou A
Front Immunol . 2024 Oct; 15:1440044. PMID: 39364402
DNA demethylases TET2 and TET3 play a fundamental role in thymic invariant natural killer T (iNKT) cell differentiation by mediating DNA demethylation of genes encoding for lineage specifying factors. Paradoxically,...

Zhou X, Wang Y, Dou Z, Delfanti G, Tsahouridis O, Pellegry C, et al.
Nat Cancer . 2024 Oct; 5(11):1607-1621. PMID: 39354225
Human natural killer T (NKT) cells have been proposed as a promising cell platform for chimeric antigen receptor (CAR) therapy in solid tumors. Here we generated murine CAR-NKT cells and...

bioRxiv . 2024 Aug; PMID: 39131272
DNA demethylases TET2 and TET3 play a fundamental role in thymic invariant natural killer T (iNKT) cell differentiation by mediating DNA demethylation of genes encoding for lineage specifying factors. Paradoxically,...

Theofilatos D, Ho T, Waitt G, Aijo T, Schiapparelli L, Soderblom E, et al.
iScience . 2024 May; 27(5):109782. PMID: 38711449
Ten-eleven translocation (TET) proteins are DNA dioxygenases that mediate active DNA demethylation. TET3 is the most highly expressed TET protein in thymic developing T cells. TET3, either independently or in...

Gioulbasani M, Tsagaratou A
Curr Protoc . 2023 Jul; 3(7):e838. PMID: 37428873
This article discusses methods to assess invariant natural killer T (iNKT) cell subsets isolated from the thymus, as well as the spleen, the liver, and the lung. iNKT cells can...

Immunohorizons . 2023 Jan; 7(1):106-115. PMID: 36645853
Ten-eleven translocation (TET) proteins are dioxygenases that oxidize 5-methylcytosine to form 5-hydroxymethylcytosine and downstream oxidized modified cytosines. In the past decade, intensive research established that TET-mediated DNA demethylation is critical...

Theofilatos D, Aijo T, Tsagaratou A
STAR Protoc . 2022 Nov; 3(4):101839. PMID: 36386867
Here, we describe steps to isolate mature thymic T cell subsets, namely CD4 single positive (SP), CD8 SP, and invariant natural killer T (iNKT) cells starting from murine total thymocytes...

Aijo T, Theofilatos D, Cheng M, Smith M, Xiong Y, Baldwin A, et al.
Front Immunol . 2022 Aug; 13:940995. PMID: 35990681
TET proteins mediate DNA demethylation by oxidizing 5-methylcytosine to 5-hydroxymethylcytosine (5hmC) and other oxidative derivatives. We have previously demonstrated a dynamic enrichment of 5hmC during T and invariant natural killer...
