Abstract
Membrane interacting peptides are reviewed in terms of structure and mode of action on lipid membranes. Helical, -stranded, peptides containing both helices and strands, cyclic, lipopeptides and short linear peptides are seen to considerably modulate membrane function. Among peptides that lead to membrane alteration or permeation, antimicrobial peptides play an important role and some of them may be foreseen as potential new antibiotics. Alternatively, peptides that do not destroy the membrane are also very important in modulating the structure and dynamics of the lipid bilayer and play important roles in membrane protein functions. Peptide lipid complexes are shown to be very variable in structure and dynamics: “carpet”, “barrel stave”, toroid and disordered pores, electrostatic wedge and molecular electroporation models are discussed. Their assembly is reviewed in terms of electric, amphipathic and dynamic properties of both lipids and peptides.
Keywords: Helical-, beta-sheet-, cyclic-, linear-peptides, membrane leakage, membrane reinforcement, membrane crossing, NMR, IR, CD, X-rays, electron microscopy, molecular dynamics.

Nutrition and Metabolism in Musculoskeletal Diseases
The musculoskeletal system consists mainly of cartilage, bone, muscles, tendons, connective tissue and ligaments. Balanced metabolism is of vital importance for the homeostasis of the musculoskeletal system. A series of musculoskeletal diseases (for example, sarcopenia, osteoporosis) are resulted from the dysregulated metabolism of the musculoskeletal system. Furthermore, metabolic diseases (such ...read more
Protein Folding, Aggregation and Liquid-Liquid Phase Separation
Protein folding, misfolding and aggregation remain one of the main problems of interdisciplinary science not only because many questions are still open, but also because they are important from the point of view of practical application. Protein aggregation and formation of fibrillar structures, for example, is a hallmark of a ...read more
