Lipocalin‐2 activates hepatic stellate cells and promotes nonalcoholic steatohepatitis in high‐fat diet–fed Ob/Ob mice

open access: yesHepatology, EarlyView., 2022
Graphical summary of obesity‐induced NASH progression by LCN2 targeted to HSC activation. Abstract Background and Aims In obesity and type 2 diabetes mellitus, leptin promotes insulin resistance and contributes to the progression of NASH via activation of hepatic stellate cells (HSCs).

RelB reduces thymocyte apoptosis and regulates terminal thymocyte maturation [PDF]

open access: yesEuropean Journal of Immunology, 2002
Thymocyte maturation is controlled by successive developmental checkpoints connected to the acquisition of a functional T cell receptor (TCR). During thymocyte selection, engagement of the TCR regulates the fine balance between death and survival signals.

Asymmetric thymocyte death underlies the CD4:CD8 T-cell ratio in the adaptive immune system [PDF]

open access: yes, 2013
It has long been recognized that the T-cell compartment has more CD4 helper than CD8 cytotoxic T cells, and this is most evident looking at T-cell development in the thymus.

From Development to Aging: Dynamic Roles of the Thymic Medulla in T Cell Biology. [PDF]

open access: yesImmunol Rev
ABSTRACT The thymic medulla is essential for establishing central tolerance, orchestrating the development of a diverse yet self‐tolerant T cell repertoire, and preventing autoimmunity. This process is primarily mediated through interactions between developing thymocytes and antigen‐presenting cells, including thymic epithelial cells (TECs) and ...

NFAT Factors Are Dispensable for the Development but Are Critical for the Maintenance of Foxp3+ Regulatory T Cells

open access: yesCells, 2022
The transcription factors of the nuclear factor of activated T cell (NFAT) family play a crucial role in multiple aspects of T cell function. It has recently been reported that NFATs play an important role in the suppressive function of CD4+CD25+Foxp3 ...

Phosphatidylinositol 3-kinase improves the efficiency of positive selection [PDF]

open access: yes, 2006
We have generated transgenic mice expressing the amino-terminal fragment of the phosphatidylinositol 3-kinase (PI3K) catalytic subunit (p110(ABD)) in thymocytes.

A novel TCR transgenic model reveals that negative selection involves an immediate, Bim-dependent pathway and a delayed, Bim-independent pathway. [PDF]

open access: yesPLoS ONE, 2010
A complete understanding of negative selection has been elusive due to the rapid apoptosis and clearance of thymocytes in vivo. We report a TCR transgenic model in which expression of the TCR during differentiation occurs only after V(D)J-like ...

The Timing and Abundance of IL-2Rβ (CD122) Expression Control Thymic iNKT Cell Generation and NKT1 Subset Differentiation

open access: yesFrontiers in Immunology, 2021
Invariant NKT (iNKT) cells are thymus-generated innate-like T cells, comprised of three distinct subsets with divergent effector functions. The molecular mechanism that drives the lineage trifurcation of immature iNKT cells into the NKT1, NKT2, and NKT17

MARCH1 protects the lipid raft and tetraspanin web from MHCII proteotoxicity in dendritic cells [PDF]

open access: yes, 2018
Dendritic cells (DCs) produce major histocompatibility complex II (MHCII) in large amounts to function as professional antigen presenting cells. Paradoxically, DCs also ubiquitinate and degrade MHCII in a constitutive manner.
