Peptide Fraction Inhibiting Plant Pathogen Growth Predominated in Cell Wall Extracts from Young Plants or in Soluble Cell Fraction from Expanded leaves from Eggplants

The Effects of Candida Albicans Cell Wall Protein Fraction on Dendritic Cell Maturation

Back ground: Candida albicans is a member of the normal human microflora. C. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in C. albicans interaction with the host immune system. Major components of C. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...

Preparation and characterization of a soluble precipitating antigen from African horsesickness virus propagated in cell cultures

Specific Binding of the Syringolide Elicitors to a Soluble Protein Fraction from Soybean Leaves.

Syringolides are glycolipid elicitors produced by Gram-negative bacteria expressing Pseudomonas syringae avirulence gene D. The syringolides mediate gene-for-gene complementarity, inducing the hypersensitive response only in soybean plants carrying the Rpg4 disease resistance gene. A site(s) for 125I-syringolide 1 was detected in the soluble protein fraction from soybean leaves, but no evidence...

Identification of Protective Pneumococcal TH17 Antigens from the Soluble Fraction of a Killed Whole Cell Vaccine

Mucosal or parenteral immunization with a killed unencapsulated pneumococcal whole cell antigen (WCA) with an adjuvant protects mice from colonization by a T(H)17 CD4+ cell-mediated mechanism. Using preparative SDS gels, we separated the soluble proteins that compose the WCA in order to identify fractions that were immunogenic and protective. We screened these fractions for their ability to sti...

Biological Study from Ruta Plants Extracts Growing in Tunisia

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...
