Editorial: Membrane lipids in T cell functions [PDF]

, 2018
Plasma membrane lipids play essential roles in regulating T cell signaling, differentiation, and effector functions. The major lipid species in the plasma membrane are glycerophospholipids, sphingolipids, and sterol lipids.

Transport of cholesterol from the endoplasmic reticulum to the plasma membrane is constitutive in CaCo-2 cells and differs from the transport of plasma membrane cholesterol to the endoplasmic reticulum

Journal of Lipid Research, 1998
The transport of newly synthesized cholesterol from its site of synthesis, the endoplasmic reticulum, to the plasma membrane was studied in CaCo-2 cells. The appearance of newly synthesized cholesterol on the cell surface was rapid. By 30 min, 50% of the

Plasma Membrane Phosphatidylinositol-4-Phosphate Is Not Necessary for Candida albicans Viability yet Is Key for Cell Wall Integrity and Systemic Infection

mBio, 2022
Phosphatidylinositol phosphates are key phospholipids with a range of regulatory roles, including membrane trafficking and cell polarity. Phosphatidylinositol-4-phosphate [PI(4)P] at the Golgi apparatus is required for the budding-to-filamentous-growth ...

High-Resolution Plasma Membrane-Selective Imaging by Second Harmonic Generation

iScience, 2018
Summary: The plasma membrane is the site of intercellular communication and subsequent intracellular signal transduction. The specific visualization of the plasma membrane in living cells, however, is difficult using fluorescence-based techniques owing ...

Distribution of cortical endoplasmic reticulum determines positioning of endocytic events in yeast plasma membrane. [PDF]

PLoS ONE, 2012
In many eukaryotes, a significant part of the plasma membrane is closely associated with the dynamic meshwork of cortical endoplasmic reticulum (cortical ER).

Visualization of the exocyst complex dynamics at the plasma membrane of Arabidopsis thaliana [PDF]

, 2013
The exocyst complex, an effector of Rho and Rab GTPases, is believed to function as an exocytotic vesicle tether at the plasma membrane before soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex formation.

Pseudomonas Lipodepsipeptides and Fungal Cell Wall-Degrading Enzymes Act Synergistically in Biological Control

Molecular Plant-Microbe Interactions, 2002
Pseudomonas syringae pv. syringae strain B359 secreted two main lipodepsipeptides (LDPs), syringomycin E (SRE) and syringopeptin 25A (SP25A), together with at least four types of cell wall—degrading enzymes (CWDEs).

In vivo analysis of protein crowding within the nuclear pore complex in interphase and mitosis

Scientific Reports, 2017
The central channel of the nuclear pore complex (NPC) is occupied by non-structured polypeptides with a high content of Phe-Gly (FG) motifs. This protein-rich environment functions as an entropic barrier that prevents the passage of molecules, as well as

Find_plasma_membrane and measure_plasma_membrane: ImageJ macros for efficient identification of and measurements at and around the plasma membrane

SoftwareX, 2023
The plasma membrane that encloses cells is difficult to precisely delineate but this is often required for quantitation of fluorescence images. We have created an ImageJ macro that efficiently maps the plasma membrane based on a few imprecisely marked ...

Lectin-based food poisoning: a new mechanism of protein toxicity. [PDF]

PLoS ONE, 2007
BACKGROUND: Ingestion of the lectins present in certain improperly cooked vegetables can result in acute GI tract distress, but the mechanism of toxicity is unknown.
