Electrical impulses evoked activity patterns in ventral tegmental area and locus coeruleus modulate endogenous and learning-dependent disparity of cell proliferation along the mouse dentate gyrus

open access: yesIBRO Neuroscience Reports, 2023
This study aimed to examine the effects of the ventral tegmental area (VTA) and the locus coeruleus (LC) patterned electrical stimulation on hippocampal-dependent learning and hippocampal neurogenesis in adult mouse.

Antibody Stimulation of Tumor Cells

open access: yesExperimental Biology and Medicine, 1977
SummaryAntiserum to normal dog kidney cells was found to stimulate cell division in a transformed dog kidney cell line. The stimulation is obtained with the γ-globulin fraction of the antiserum and the effect is removed by absorption of the antiserum with either the transformed dog kidney cell or with primary dog kidney cells.

Single-cell states in the estrogen response of breast cancer cell lines [PDF]

open access: yes, 2014
Estrogen responsive breast cancer cell lines have been extensively studied to characterize transcriptional patterns in hormone-responsive tumors. Nevertheless, due to current technological limitations, genome-wide studies have typically been limited to ...

"Tolerization" of human T-helper cell clones by chronic exposure to alloantigen [PDF]

open access: yes, 1988
Induction of clonal anergy in T-helper (Th) cells may have a role in regulating immune responses. A model system for studying Th cell tolerization at the clonal level in vitro could be useful for investigating the mechanisms involved.

The zinc finger transcription factor Early Growth Response 2 (Egr-2) is an intrinsic regulator of T cell tolerance and homeostasis [PDF]

open access: yes, 2009
PhDTolerance of T cells to self-antigen is crucial to prevent the development of autoimmune disease. How self-tolerance is controlled at the transcriptional level is, however, unknown. We discovered that the transcription factor Early Growth Response 2

Comparison of stimulation patterns for FES-cycling using measures of oxygen cost and stimulation cost [PDF]

open access: yes, 2006
<b>Aim</b><p></p> The energy efficiency of FES-cycling in spinal cord injured subjects is very much lower than that of normal cycling, and efficiency is dependent upon the parameters of muscle stimulation.
