Efe O, Gassen R, Morena L, Ganchiku Y, Al Jurdi A, Lape I, et al.
J Clin Invest . 2024 Mar; 134(5). PMID: 38426492
Long-term organ transplant survival remains suboptimal, and life-long immunosuppression predisposes transplant recipients to an increased risk of infection, malignancy, and kidney toxicity. Promoting the regulatory arm of the immune system...

Zhai N, Liu W, Jin C, Ding Y, Sun L, Zhang D, et al.
J Immunol . 2023 Jul; 211(5):885-894. PMID: 37486211
IFN-γ is a pleiotropic cytokine that plays a controversial role in regulatory T cell (Treg) activity. In this study, we sought to understand how IFN-γ receptor (IFN-γR) signaling affects donor...

Poznansky S, Yu M, Deng K, Fu Q, Markmann J, LeGuern C
Front Immunol . 2023 May; 14:1173672. PMID: 37180165
A subset of B-cells with tolerogenic functions, termed B-regulatory cells or Bregs, is characterized by the expression of anti-inflammatory/tolerogenic cytokines, namely IL-10, TGF-β, and IL-35, that contribute to their regulatory...

Lee K, Fu Q, Huai G, Deng K, Lei J, Kojima L, et al.
JCI Insight . 2022 Aug; 7(17). PMID: 35943811
B lymphocytes have long been recognized for their critical contributions to adaptive immunity, providing defense against pathogens through cognate antigen presentation to T cells and Ab production. More recently appreciated...

Matheson R, Deng K, Huai G, Lee K, Feeney N, Coe T, et al.
Transplant Rev (Orlando) . 2021 Dec; 36(1):100674. PMID: 34861509
Transplantation of xenogeneic organs is an attractive solution to the existing organ shortage dilemma, thus, securing a clinically acceptable prolongation of xenograft survival is an important goal. In preclinical transplantation...

Fu Q, Lee K, Huai G, Deng K, Agarwal D, Rickert C, et al.
Am J Transplant . 2021 Jul; 21(12):3847-3857. PMID: 34327838
Regulatory B cells (Bregs) have shown promise as anti-rejection therapy applied to organ transplantation. However, less is known about their effect on other B cell populations that are involved in...

Tanimine N, Burrell B, Deng K, Rickert C, Lee K, Feeney N, et al.
J Immunol Methods . 2021 Feb; 491:112987. PMID: 33556344
Precise analyses of alloreactive T cell phenotype and function can inform both the nature and intensity of adaptive responses to transplant antigens. However, alloreactive T cells are sparse and difficult...

LeGuern C, Germana S
Am J Transplant . 2018 Nov; 19(1):15-20. PMID: 30378738
Therapies using thymus-derived regulatory T cells (Tregs) are promising strategies for preventing autoimmunity or graft rejection. The efficacy of these approaches is, however, contingent on a better understanding of Treg...
