False-negative synovial alpha-defensin

Arthroplasty Today, 2017
We present a case of chronic periprosthetic hip infection diagnosed using the Musculoskeletal Infection Society criteria as the gold standard. The alpha-defensin test was falsely negative.

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.

Comparative genomic identification and validation of β-defensin genes in the Ovis aries genome

BMC Genomics, 2017
Background β-defensins are small, cationic, antimicrobial peptides found in species across the plant and animal kingdoms. In addition to microbiocidal activity, roles in immunity as well as reproduction have more recently been documented.

Structural and Stability Analysis of de Novo Designed Proteins Incorporating a Plant Self‐Incompatibility Motif

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Artificial protein design enables the creation of stable scaffolds beyond those evolved in nature. Incorporation of native functional motifs into de novo scaffolds provides a promising strategy to mimic natural interactions while altering structural frameworks.

Role of defensins in immunothrombosis

Rheumatology &Autoimmunity, EarlyView.
Defensins are important proteins that link the immune system and blood clotting, playing a key role in immunothrombosis. α‐defensins mainly come from neutrophils, while β‐defensins are produced by epithelial cells and platelets. These proteins help form blood clots in several ways: they slow down clot breakdown (fibrinolysis), activate platelets, and ...

Peptide‐based antibacterial nanoplatforms: Design principles, stimuli‐regulated behaviors, and applications

Responsive Materials, EarlyView.
Peptide‐based antibacterial nanoplatforms, encompassing self‐assembled peptides and peptide‐engineered inorganic, polymeric, and lipid nanocarriers, are systematically reviewed. The article highlights design principles and stimuli‐responsive regulation for improving peptide stability, delivery efficiency, and antibacterial performance.

Manual annotation and analysis of the defensin gene cluster in the C57BL/6J mouse reference genome

BMC Genomics, 2009
Background Host defense peptides are a critical component of the innate immune system. Human alpha- and beta-defensin genes are subject to copy number variation (CNV) and historically the organization of mouse alpha-defensin genes has been poorly defined.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Effects of Dietary Vitamin D3 Supplementation on AvBD-1 and chCATH-1 Genes Expression in Chicken

The Journal of Poultry Science, 2011
In addition to the important role in maintaining calcium homeostasis, vitamin D3 (VD3) has also been suggested to participate in the regulation of innate and adaptive immune responses in human by enhancing antimicrobial peptides expression.
