Polarization of macrophages toward M2 phenotype is favored by reduction in iPLA2β (group VIA phospholipase A2)* [PDF]

open access: yes, 2016
Macrophages are important in innate and adaptive immunity. Macrophage participation in inflammation or tissue repair is directed by various extracellular signals and mediated by multiple intracellular pathways.

Novel Bradykinin-Potentiating Peptides and Three-Finger Toxins from Viper Venom: Combined NGS Venom Gland Transcriptomics and Quantitative Venom Proteomics of the Azemiops feae Viper

open access: yesBiomedicines, 2020
Feae’s viper Azemipos feae belongs to the Azemiopinae subfamily of the Viperidae family. The effects of Viperidae venoms are mostly coagulopathic with limited neurotoxicity manifested by phospholipases A2. From A.

Phospholipases and Membrane Curvature: What Is Happening at the Surface?

open access: yesMembranes, 2023
In this revision work, we emphasize the close relationship between the action of phospholipases and the modulation of membrane curvature and curvature stress resulting from this activity.

Bacterial phospholipase A: structure and function of an integral membrane phospholipase [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2000
Within the large family of lipolytic enzymes, phospholipases constitute a very diverse subgroup with physiological functions such as digestion and signal transduction. Most phospholipases may associate with membranes at the lipid-water interface. However, in many Gram-negative bacteria, a phospholipase is present which is located integrally in the ...

Low-level laser therapy decreases local effects induced by myotoxins isolated from Bothrops jararacussu snake venom [PDF]

open access: yes, 2010
The prominent myotoxic effects induced by Bothrops jararacussu crude venom are due, in part, to its polycationic myotoxins, BthTX-I and BthTX-II. Both myotoxins have a phospholipase A2 structure: BthTX-II is an active enzyme Asp-49 PLA2, while BthTX-I is

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The Phospholipases A of Epidermis

open access: yesJournal of Investigative Dermatology, 1980
Phospholipases A have been characterized in fetal rat epidermis. Both a calcium dependent phospholipase A with pH optimum of 8.5 and a calcium independent enzyme with a pH optimum of 4.5 were found. Activity against both acyl groups of phosphatidyl choline were found for both enzymes and the findings suggested that the acid enzyme (pH 4.5) is primarily

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Phospholipase A2 as a mechanosensor

open access: yesBiophysical Journal, 1995
Osmotic swelling of large unilamellar vesicles (LUVs) causes membrane stretching and thus reduces the lateral packing of lipids. This is demonstrated to modulate strongly the catalytic activity of phospholipase A2 (PLA2) toward a fluorescent phospholipid, 1-palmitoyl-2-[(6-pyren-1-yl)]decanoyl-sn-glycero-3-phosphocholine (PPDPC) residing in LUVs ...
