Modulation of TCR signalling components occurs prior to positive selection and lineage commitment in iNKT cells

open access: yesScientific Reports, 2021
iNKT cells play a critical role in controlling the strength and character of adaptive and innate immune responses. Their unique functional characteristics are induced by a transcriptional program initiated by positive selection mediated by CD1d expressed

The differentiation and integration of the hippocampal dorsoventral axis are controlled by two nuclear receptor genes

open access: yeseLife, 2023
The hippocampus executes crucial functions from declarative memory to adaptive behaviors associated with cognition and emotion. However, the mechanisms of how morphogenesis and functions along the hippocampal dorsoventral axis are differentiated and ...

Beta cell identity changes with mild hyperglycemia: Implications for function, growth, and vulnerability

open access: yesMolecular Metabolism, 2020
Objective: As diabetes develops, marked reductions of insulin secretion are associated with very modest elevations of glucose. We wondered if these glucose changes disrupt beta cell differentiation enough to account for the altered function.

Role of Akt/Protein Kinase B in Cancer Metastasis

open access: yesBiomedicines, 2023
Metastasis is a critical step in the process of carcinogenesis and a vast majority of cancer-related mortalities result from metastatic disease that is resistant to current therapies.

A Peroxiredoxin Promotes H2O2 Signaling and Oxidative Stress Resistance by Oxidizing a Thioredoxin Family Protein

open access: yesCell Reports, 2013
H2O2 can cause oxidative damage associated with age-related diseases such as diabetes and cancer but is also used to initiate diverse responses, including increased antioxidant gene expression.

Cl-out is a novel cooperative optogenetic tool for extruding chloride from neurons

open access: yesNature Communications, 2016
Chloride regulation is important for setting GABAergic reversal potential, though tools to manipulate chloride levels are limited. Here, the authors combine Archaerhodopsin with a chloride channel opsin to generate an optogenetic chloride extrusion ...

Engineered kinesin motor proteins amenable to small-molecule inhibition

open access: yesNature Communications, 2016
The use of specific small molecule inhibitors can contribute to the study of kinesins' cellular functions. Here the authors develop a chemical-genetic approach to engineer kinesin motors that can be efficiently inhibited upon addition of cell-permeable ...
