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.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

A Novel β-Defensin Structure: Big Defensin Changes Its N-Terminal Structure To Associate with the Target Membrane

, 2016
Big defensin is a 79-residue peptide derived from hemocytes of the Japanese horseshoe crab. The amino acid sequence of big defensin is divided into an N-terminal hydrophobic domain and a C-terminal cationic domain, which are responsible for antimicrobial

RNA activation in insects: From emerging evidence to molecular applications

Insect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Diversity and inter-connections in the CXCR4 chemokine receptor/ligand family: molecular perspectives

Frontiers in Immunology, 2015
CXCR4 and its ligand CXCL12 mediate the homing of progenitor cells in the bone marrow and their recruitment to sites of injury, as well as affect processes such as cell arrest, survival and angiogenesis.

Alpha-defensin increase in peripheral blood mononuclear cells from patients with hepatitis C virus chronic infection

, 2006
SUMMARY. Thea-defensin genes promoter regions contain a putative nuclear factors of activated T cells (NFAT)-binding site and it is known that hepatitis C virus (HCV) core protein activates the interleukin (IL)-2 gene transcription through the NFAT ...

STAG Priming Preserves Paneth Cells and Limits Parasite‐Triggered Ileitis

Immunology &Cell Biology, EarlyView.
Preservation of Paneth cells is associated with resistance to ileitis caused by Toxoplasma gondii. ABSTRACT Toxoplasma gondii triggered ileitis is a commonly used model for diseases affecting the small intestine, such as Crohn's Disease. Inflammation is primarily dependent on Th1‐mediated killing of Paneth cells, which consequently promotes intestinal ...

Milk‐Derived Signals Guide Neonatal Hematopoiesis and Respiratory Defense

Immunology &Cell Biology, EarlyView.
This commentary summarises a recent paper in Cell by Howard et al. showing that osteopontin shapes the infant microbiome, which in turn directs early immune development in the airways. This early programming confers protection against respiratory tract infections that persists well beyond infancy.

From venom peptides to neurotherapeutics: BmK defensins and short-chain peptides as modulators of ion channels

Frontiers in Pharmacology
Scorpions, having inhabited the Earth long before the emergence of humans, represent an ancient lineage of arthropods. While often regarded with fear due to their potential to induce severe pain or fatal envenomation, scorpion venoms constitute complex ...

Comparative Analysis of the Nodule Transcriptomes of Ceanothus thyrsiflorus (Rhamnaceae, Rosales) and Datisca glomerata (Datiscaceae, Cucurbitales)

Frontiers in Plant Science, 2018
Two types of nitrogen-fixing root nodule symbioses are known, rhizobial and actinorhizal symbioses. The latter involve plants of three orders, Fagales, Rosales, and Cucurbitales.
