Cell signaling promoting protein carbonylation does not cause sulfhydryl oxidation: implications to the mechanism of redox signaling [PDF]

open access: yes, 2017
Reactive oxygen species (ROS) have been recognized as second messengers, however, targeting mechanisms for ROS in cell signaling have not been defined.

Mechanical stimulation promotes enthesis injury repair by mobilizing Prrx1+ cells via ciliary TGF-β signaling

open access: yeseLife, 2022
Proper mechanical stimulation can improve rotator cuff enthesis injury repair. However, the underlying mechanism of mechanical stimulation promoting injury repair is still unknown. In this study, we found that Prrx1+ cell was essential for murine rotator

BAFF activation of the ERK5 MAP kinase pathway regulates B cell survival [PDF]

open access: yes, 2015
B cell activating factor (BAFF) stimulation of the BAFF receptor (BAFF-R) is essential for the homeostatic survival of mature B cells. Earlier in vitro experiments with inhibitors that block MEK 1 and 2 suggested that activation of ERK 1 and 2 MAP ...

Organic photovoltaic device enhances the neural differentiation of rat bone marrow-derived mesenchymal stem cells

open access: yesMedicine in Novel Technology and Devices, 2022
Electrical stimulation is known to be involved in stem cell differentiation, particularly neural differentiation. Various electrical stimulation systems and devices have been developed for neural tissue engineering. The organic photovoltaic materials PM6

Postsynaptic Ca2+, but not cumulative depolarization, is necessary for the induction of associative plasticity in Hermissenda [PDF]

open access: yes, 1993
The neuronal modifications that underlie associative memory in Hermissenda have their origins in a synaptic interaction between the visual and vestibular systems, and can be mimicked by contiguous in vitro stimulation of these converging pathways. At the

CCCTC-binding factor locks premature IgH germline transcription and restrains class switch recombination [PDF]

open access: yes, 2017
In response to antigenic stimulation B cells undergo class switch recombination (CSR) at the immunoglobulin heavy chain (IgH) to replace the primary IgM/IgD isotypes by IgG, IgE, or IgA.

Stimulation of incretin secreting cells [PDF]

open access: yesTherapeutic Advances in Endocrinology and Metabolism, 2015
The incretin hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon like peptide-1 (GLP-1) are secreted from enteroendocrine cells in the gut and regulate physiological and homeostatic functions related to glucose control, metabolism and food intake.

Skeletal muscle cells opto-stimulation by intramembrane molecular transducers

open access: yesCommunications Biology, 2023
Optical stimulation and control of muscle cell contraction opens up a number of interesting applications in hybrid robotic and medicine. Here we show that recently designed molecular phototransducer can be used to stimulate C2C12 skeletal muscle cells ...

Quantification of IFNγ- and IL17-producing cells after stimulation with citrullinated proteins in healthy subjects and RA patients [PDF]

open access: yes, 2013
Antibodies against citrullinated proteins are highly specific for rheumatoid arthritis (RA) and are currently used as a diagnostic marker. In this study, we wanted to quantify the numbers of T cells that react to a wide range of citrullinated proteins in

PD-1 Primarily Targets TCR Signal in the Inhibition of Functional T Cell Activation

open access: yesFrontiers in Immunology, 2019
Cancer-immunotherapy targeting programmed cell death 1 (PD-1) activates tumor-specific T cells and provides clinical benefits in various cancers. However, the molecular basis of PD-1 function is still enigmatic.
