Sakthivel D, Brown-Suedel A, Lopez K, Salgar S, Coutinho L, Keane F, et al.
Sci Adv . 2024 Aug; 10(31):eadj3145. PMID: 39093977
Mutation in nucleophosmin (NPM1) causes relocalization of this normally nucleolar protein to the cytoplasm (NPM1c+). Despite NPM1 mutation being the most common driver mutation in cytogenetically normal adult acute myeloid...

Smith M, Forbes Satter L, Vargas-Hernandez A
Front Immunol . 2023 Feb; 13:1025373. PMID: 36755813
The Signal Transducer and Activator of Transcription (STAT)-5 proteins are required in immune regulation and homeostasis and play a crucial role in the development and function of several hematopoietic cells....

Leiding J, Vogel T, Santarlas V, Mhaskar R, Smith M, Carisey A, et al.
J Allergy Clin Immunol . 2022 Oct; 151(4):1081-1095. PMID: 36228738
Background: In 2014, germline signal transducer and activator of transcription (STAT) 3 gain-of-function (GOF) mutations were first described to cause a novel multisystem disease of early-onset lymphoproliferation and autoimmunity. Objective:...

Pelham S, Caldirola M, Avery D, Mackie J, Rao G, Gothe F, et al.
J Allergy Clin Immunol . 2022 Apr; 150(4):931-946. PMID: 35469842
Background: Lymphocyte differentiation is regulated by coordinated actions of cytokines and signaling pathways. IL-21 activates STAT1, STAT3, and STAT5 and is fundamental for the differentiation of human B cells into...

Front Immunol . 2022 Feb; 12:810080. PMID: 35173710
Human NK cells are comprised of phenotypic subsets, whose potentially unique functions remain largely unexplored. C-X-C-motif-chemokine-receptor-6 (CXCR6) NK cells have been identified as phenotypically immature tissue-resident NK cells in mice...

Cook S, Comrie W, Poli M, Similuk M, Oler A, Faruqi A, et al.
Science . 2020 Jul; 369(6500):202-207. PMID: 32647003
Immunodeficiency often coincides with hyperactive immune disorders such as autoimmunity, lymphoproliferation, or atopy, but this coincidence is rarely understood on a molecular level. We describe five patients from four families...

Kuhny M, Forbes L, Cakan E, Vega-Loza A, Kostiuk V, Dinesh R, et al.
J Clin Invest . 2020 Jun; 130(8):4411-4422. PMID: 32484799
Patients with common variable immunodeficiency associated with autoimmune cytopenia (CVID+AIC) generate few isotype-switched B cells with severely decreased frequencies of somatic hypermutations (SHMs), but their underlying molecular defects remain poorly...

Vargas-Hernandez A, Witalisz-Siepracka A, Prchal-Murphy M, Klein K, Mahapatra S, Al-Herz W, et al.
J Allergy Clin Immunol . 2019 Oct; 145(1):345-357.e9. PMID: 31600547
Background: Patients with signal transducer and activator of transcription 5b (STAT5b) deficiency have impairment in T-cell homeostasis and natural killer (NK) cells which leads to autoimmunity, recurrent infections, and combined...

Nuclear factor kappa-B subunit 2 (NF-κB2/p100/p52), encoded by (MIM: 164012) belongs to the NF-κB family of transcription factors that play a critical role in inflammation, immunity, cell proliferation, differentiation and...

Front Pediatr . 2019 May; 7:160. PMID: 31114772
In this report, we describe a novel T437N STAT1 mutation found in a mother and 3 of her 4 children which we demonstrate yields gain-of-function. All of the four patients...
