Assessment of antimicrobial, antiproliferative, and chemotactic properties of ranatuerin 2-PMe from cutaneous secretion of Lithobates palmipes (Spix, 1824) (Anura, Ranidae).

Lithobates palmipes is a frog species whose skin secretions contain peptides belonging to the ranatuerin, brevinin, and temporin families. In this study, the peptide ranatuerin-2PMe was isolated and evaluated for its antimicrobial, hemolytic, antiproliferative, and chemotactic activities. Ranatuerin-2PMe (2933.

Proteomics: Unraveling the Cross Talk Between Innate Immunity and Disease Pathophysiology, Diagnostics, and Treatment Options.

Inflammation is crucial in diseases, and proteins play a key role in the interplay between innate immunity and pathology. This review explores how proteomics helps understanding this relationship, focusing on diagnosis and treatment. We explore the dynamic innate response and the significance of proteomic techniques in deciphering the complex network of proteins involved in prevalent diseases, including infections, cancer, autoimmune and neurodegenerative disorders.

A Set of Screening Techniques for a Quick Overview of the Neutrophil Function.

Neutrophils are known as one of the first lines of defense in the innate immune response and can perform many particular cellular functions, such as chemotaxis, reverse migration, phagocytosis, degranulation of cytotoxic enzymes and metabolites, and release of DNA as neutrophil extracellular traps (NETs). Neutrophils not only have tightly regulated signaling themselves, but also participate in the regulation of other components of the immune system. As fresh neutrophils are terminally differentiated, short-lived, and highly variable among individuals, it is important to make the most of the collected samples.
