Ubiquitin-Mediated Regulation of RIPK1 Kinase Activity Independent of IKK and MK2.
(CELL PRESS, 2018-02-15)
Tumor necrosis factor (TNF) can drive inflammation, cell survival, and death. While ubiquitylation-, phosphorylation-, and nuclear factor κB (NF-κB)-dependent checkpoints suppress the cytotoxic potential of TNF, it remains ...
Checkpoints in TNF-Induced Cell Death: Implications in Inflammation and Cancer.
(ELSEVIER SCI LTD, 2018-01-01)
Tumor necrosis factor (TNF) is a proinflammatory cytokine that coordinates tissue homeostasis by regulating cytokine production, cell survival, and cell death. However, how life and death decisions are made in response to ...
The Diversification of Cell Death and Immunity: Memento Mori.
(CELL PRESS, 2019-10-01)
Why do cells have so many ways to die? Why does "cellular suicide" exist at all? In the war against pathogens and rogue cells, organisms developed cellular suicide as a last resort. Fighting an evolutionary arms race, cell ...
The NMDA receptor regulates competition of epithelial cells in the Drosophila wing.
(NATURE PUBLISHING GROUP, 2020-05-06)
Cell competition is an emerging principle that eliminates suboptimal or potentially dangerous cells. For 'unfit' cells to be detected, their competitive status needs to be compared to the collective fitness of cells within ...
Cleavage of cFLIP restrains cell death during viral infection and tissue injury and favors tissue repair.
(AMER ASSOC ADVANCEMENT SCIENCE, 2023-07-28)
Cell death coordinates repair programs following pathogen attack and tissue injury. However, aberrant cell death can interfere with such programs and cause organ failure. Cellular FLICE-like inhibitory protein (cFLIP) is ...
MK2 Phosphorylates RIPK1 to Prevent TNF-Induced Cell Death.
(CELL PRESS, 2017-06-01)
TNF is an inflammatory cytokine that upon binding to its receptor, TNFR1, can drive cytokine production, cell survival, or cell death. TNFR1 stimulation causes activation of NF-κB, p38α, and its downstream effector kinase ...
An inhibitory mono-ubiquitylation of the Drosophila initiator caspase Dronc functions in both apoptotic and non-apoptotic pathways.
(PUBLIC LIBRARY SCIENCE, 2017-02-01)
Apoptosis is an evolutionary conserved cell death mechanism, which requires activation of initiator and effector caspases. The Drosophila initiator caspase Dronc, the ortholog of mammalian Caspase-2 and Caspase-9, has an ...
The regulatory isoform rPGRP-LC induces immune resolution via endosomal degradation of receptors.
(NATURE PUBLISHING GROUP, 2016-08-22)
The innate immune system needs to distinguish between harmful and innocuous stimuli to adapt its activation to the level of threat. How Drosophila mounts differential immune responses to dead and live Gram-negative bacteria ...
PIM1 kinase regulates cell death, tumor growth and chemotherapy response in triple-negative breast cancer.
(NATURE PUBLISHING GROUP, 2016-11-01)
Triple-negative breast cancers (TNBCs) have poor prognosis and lack targeted therapies. Here we identified increased copy number and expression of the PIM1 proto-oncogene in genomic data sets of patients with TNBC. TNBC ...
RET Functions as a Dual-Specificity Kinase that Requires Allosteric Inputs from Juxtamembrane Elements.
(CELL PRESS, 2016-12-20)
Receptor tyrosine kinases exhibit a variety of activation mechanisms despite highly homologous catalytic domains. Such diversity arises through coupling of extracellular ligand-binding portions with highly variable ...
