Human Defensins Inhibit SARS-CoV-2 Infection by Blocking Viral Entry

open access: yesViruses, 2021
Innate immunity during acute infection plays a critical role in the disease severity of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), and is likely to contribute to COVID-19 disease outcomes.

The Chemistry and Biology of Theta Defensins [PDF]

open access: yesAngewandte Chemie International Edition, 2014
AbstractCyclic peptides are found in a diverse range of organisms and are characterized by their stability and role in defense. Why is only one class of cyclic peptides found in mammals? Possibly we have not looked hard enough for them, or the technologies needed to identify them are not fully developed.

De Novo Design of Membrane‐Targeting Antimicrobial Peptides Against Gram‐Negative Bacteria Using a Generative Artificial Intelligence Framework

open access: yesAdvanced Science, EarlyView.
Antimicrobial resistance caused by Gram‐negative bacteria remains difficult to overcome due to the protective outer membrane. To address this challenge, a multi‐condition constrained generative AI framework, GenMTAMP is proposed for de novo membrane‐targeting antimicrobial peptide design by integrating physicochemical and spatial structure descriptors.

Antifungal defensins and their role in plant defense

open access: yesFrontiers in Microbiology, 2014
Since the beginning of the 90’s lots of cationic plant, cysteine-rich antimicrobial peptides (AMP) have been studied. However, Broekaert only coined the term plant defensin in 1995, after comparison of a new class of plant antifungal peptides with known

Human β-defensin 4 – defensin without the “twist”

open access: yesPostępy Biochemii, 2016
β-defensins are small, cysteine-rich, cationic peptides that contribute to various processes related to both arms of host defense, the innate and adaptive immunities. All β-defensins are potent antimicrobials with activity targeting a broad range of pathogens.

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

Biofilm Exoproteins From Staphylococcus Species Impede Re‐Epithelialization of Nasal Epithelial Cells During Wound Healing and Cease Ciliary Beat Frequency

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Chronic rhinosinusitis (CRS) is an inflammatory disease with many different contributing factors, including bacterial infection. CRS patients are typically managed with medical therapies; however, these treatments frequently fail, leaving surgery as the only viable option.

Modelling study of dimerization in mammalian defensins

open access: yesBMC Bioinformatics, 2006
Background Defensins are antimicrobial peptides of innate immunity functioning by non-specific binding to anionic phospholipids in bacterial membranes.

Cyclic and acyclic defensins inhibit human immunodeficiency virus type-1 replication by different mechanisms. [PDF]

open access: yesPLoS ONE, 2010
Defensins are antimicrobial peptides expressed by plants and animals. In mammals there are three subfamilies of defensins, distinguished by structural features: alpha, beta and theta. Alpha and beta-defensins are linear peptides with broad anti-microbial
