Intraspecific Variation of Centruroides Edwardsii Venom from Two Regions of Colombia

open access: yesToxins, 2014
We report the first description studies, partial characterization, and intraspecific difference of Centruroides edwardsii, Gervais 1843, venom. C. edwardsii from two Colombian regions (Antioquia and Tolima) were evaluated.

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 ...

Effective antiprotease-antibiotic treatment of experimental anthrax [PDF]

open access: yes, 2005
BACKGROUND: Inhalation anthrax is characterized by a systemic spread of the challenge agent, Bacillus anthracis. It causes severe damage, including multiple hemorrhagic lesions, to host tissues and organs.

ALKBH5‐Mediated M6A Demethylation of G3BP1 Attenuates Ferroptosis Via Cytoplasmic Retention of YBX1/p53 in Diabetic Myocardial Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
ALKBH5 promoted G3BP1 expression via m⁶A methylation at sites 142/173. G3BP1 interacts with YBX1 and p53, reducing their nuclear translocation and decreasing p53‐mediated SLC7A11 repression. This inhibites cardiomyocyte ferroptosis and mitigates myocardial damage during diabetic ischemia‐reperfusion injury.

Phospholipase A Activity in the Epidermis

open access: yesJournal of Investigative Dermatology, 1972
Phospholipase A activity has been demonstrated in cow snout epidermis. The activity was higher in the upper layers of the epidermis. The enzyme has been purified by preparing aqueous extracts of acetone powders obtained from epidermal homogenates. The most active preparation gave a pH optimum of 8.3 for the release of free fatty acids from phosphatidyl

Group V Secreted Phospholipase A2 Induces the Release of Proangiogenic and Antiangiogenic Factors by Human Neutrophils [PDF]

open access: yes, 2017
Secreted phospholipases A2 (sPLA2s) are extracellular enzymes that catalyze the release of free fatty acids and lysophospholipids from membrane phospholipids and also bind to different receptors (e.g., PLA2R1 or integrins).

Structural Basis of GABAB Receptor Activation during Evolution

open access: yesAdvanced Science, EarlyView.
This study explores the structural and functional mechanisms of the drosophila GABAB receptor, a key role in neurotransmission. Using cryo‐EM, the research reveals how the receptor's activation differs from its human counterpart, highlighting unique evolutionary features.

Designing New Natural‐Mimetic Phosphatidic Acid: a Versatile and Innovative Synthetic Strategy for Glycerophospholipid Research

open access: yesAngewandte Chemie International Edition, Accepted Article.
Glycerophospholipids (GPLs) play important roles in cellular compartmentalization and signaling. Among them, phosphatidic acids (PA) exist as many distinct species depending on acyl chain composition, each one potentially displaying unique signaling function.

Potential role of phospholipases in virulence and fungal pathogenesis.

open access: yesClinical Microbiology Reviews, 2000
Microbial pathogens use a number of genetic strategies to invade the host and cause infection. These common themes are found throughout microbial systems. Secretion of enzymes, such as phospholipase, has been proposed as one of these themes that are used
