The Neutral Sphingomyelinase 2 Is Required to Polarize and Sustain T Cell Receptor Signaling [PDF]

Frontiers in Immunology, 2018
By promoting ceramide release at the cytosolic membrane leaflet, the neutral sphingomyelinase 2 (NSM) is capable of organizing receptor and signalosome segregation. Its role in T cell receptor (TCR) signaling remained so far unknown. We now show that TCR-

Staying sane in the membrane: Neutral sphingomyelinase 2 as a master regulator of plasma membrane ceramide [PDF]

Journal of Lipid Research
Ceramide, a key signaling sphingolipid in the plasma membrane, plays a pivotal role in fundamental cellular processes such as adhesion, polarity, and programmed cell death.

Down‐regulation of acid sphingomyelinase and neutral sphingomyelinase‐2 inversely determines the cellular resistance to plasmalemmal injury by pore‐forming toxins [PDF]

The FASEB Journal, 2018
ABSTRACT Bacterial pore‐forming toxins compromise plasmalemmal integrity, leading to Ca 2+ influx, leakage of the cytoplasm, and cell death. Such lesions can be repaired by microvesicular shedding or by the endocytic uptake of the injured membrane sites.

Stress-induced sphingolipid signaling: role of type-2 neutral sphingomyelinase in murine cell apoptosis and proliferation. [PDF]

PLoS ONE, 2010
BACKGROUND:Sphingomyelin hydrolysis in response to stress-inducing agents, and subsequent ceramide generation, are implicated in various cellular responses, including apoptosis, inflammation and proliferation, depending on the nature of the different ...

Dual Neutral Sphingomyelinase-2/Acetylcholinesterase Inhibitors for the Treatment of Alzheimer's Disease. [PDF]

ACS Chem Biol, 2020
We report the discovery of a novel class of compounds that function as dual inhibitors of the enzymes neutral sphingomyelinase-2 (nSMase2) and acetylcholinesterase (AChE). Inhibition of these enzymes provides a unique strategy to suppress the propagation of tau pathology in the treatment of Alzheimer's disease (AD).

Role of Neutral Sphingomyelinase-2 (NSM 2) in the Control of T Cell Plasma Membrane Lipid Composition and Cholesterol Homeostasis [PDF]

Frontiers in Cell and Developmental Biology, 2019
The activity of neutral sphingomyelinase-2 (NSM2) to catalyze the conversion of sphingomyelin (SM) to ceramide and phosphocholine at the cytosolic leaflet of plasma membrane (PM) is important in T cell receptor (TCR) signaling.

Hyperosmolarity-induced lipid droplet formation depends on ceramide production by neutral sphingomyelinase 2 [PDF]

Journal of Lipid Research, 2012
Hyperosmolarity (HO) imposes a remarkable stress on membranes, especially in tissues in direct contact with the external environment. Our efforts were focused on revealing stress-induced lipid changes that precede the inflammatory cytokine response in ...

Neutral sphingomyelinase 2 is required for HIV-1 maturation. [PDF]

Proc Natl Acad Sci U S A, 2023
HIV-1 assembly occurs at the inner leaflet of the plasma membrane (PM) in highly ordered membrane microdomains. The size and stability of membrane microdomains is regulated by activity of the sphingomyelin hydrolase neutral sphingomyelinase 2 (nSMase2) that is localized primarily to the inner leaflet of the PM.
