Plasma Membrane Repair Is Regulated Extracellularly by Proteases Released from Lysosomes. [PDF]
Eukaryotic cells rapidly repair wounds on their plasma membrane. Resealing is Ca(2+)-dependent, and involves exocytosis of lysosomes followed by massive endocytosis.

Structure-based virtual screening to predict Loxosceles spider venom natural inhibitors
Objective: Loxosceles spider bite accidents are rising in wide areas of the world which necessitates the exploration of natural inhibitors to inhibit the most significant enzymes, namely sphingomyelinase D (Smase D) and hyaluronidase.

The role of the host—Neutrophil biology
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Loxoscelism: Advances and Challenges in the Design of Antibody Fragments with Therapeutic Potential
Envenoming due to Loxosceles spider bites still remains a neglected disease of particular medical concern in the Americas. To date, there is no consensus for the treatment of envenomed patients, yet horse polyclonal antivenoms are usually infused to ...

Structural Basis for Metal Ion Coordination and the Catalytic Mechanism of Sphingomyelinases D [PDF]
Sphingomyelinases D (SMases D) from Loxosceles spider venom are the principal toxins responsible for the manifestation of dermonecrosis, intravascular hemolysis, and acute renal failure, which can result in death. These enzymes catalyze the hydrolysis of sphingomyelin, resulting in the formation of ceramide 1-phosphate and choline or the hydrolysis of ...

Biotechnological potential of Phospholipase D for Loxosceles antivenom development
Loxoscelism is one of the most important forms of araneism in South America. The Health Authorities from countries with the highest incidence and longer history in registering loxoscelism cases indicate that specific antivenom should be administered ...

Niemann Pick disease: a rare lysosomal storage disease
Niemann Pick Disease (NPD) is a rare autosomal recessive lysosomal storage disease characterized by lysosomal lipid storage. The disease is caused by deficiency of enzyme, acid sphingomyelinase (ASM) which leads to accumulation of sphingomyelin & other ...
