Cat. No. : DEFB4A-037H
Description : Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The a-defensins are distinguished from the beta-defensins by the pairing of their three disulfide bonds. To date, four human beta-defensins have been identified; BD-1, BD-2, BD-3 and BD-4. beta-defensins are expressed on some leukocytes and at epithelial surfaces. In addition to their direct antimicrobial activities, they are chemoattractant towards immature dendritic cells and memory T cells.

Ask a question
How can the structure of DEFB4A be evaluated? 05/25/2023

DEFB4A has a typical β-defensin structure consisting of a cysteine-rich mature peptide region and a positively charged N-terminal region. This structure allows it to bind and destroy the cell membranes of pathogenic microorganisms.

Which biomolecules can be used as molecular markers for DEFB4A? 03/16/2023

Biomolecules that can be used as molecular markers for DEFB4A include its mRNA and protein expression products in tissues and cells, as well as other biomolecules (e.g., receptors, signal transduction molecules, etc.) that interact with it.

What diseases are associated with the aberrant expression of DEFB4A? 07/26/2022

The abnormal expression of DEFB4A is associated with a variety of inflammatory and infectious diseases, such as psoriasis, atopic dermatitis, chronic sinusitis, etc. In addition, the expression of DEFB4A has also been found to be associated with the occurrence and progression of certain tumors.

What are the treatment strategies for DEFB4A? 03/07/2021

Therapeutic strategies for DEFB4A include modulating its expression levels, enhancing its antimicrobial activity, and developing inhibitors targeting its signaling pathway. Treatment depends on the type and severity of the disease.

How can I detect the expression level of DEFB4A? 11/15/2020

The mRNA and protein expression levels of DEFB4A in tissues and cells can be detected by real-time PCR, immunohistochemistry, and western blotting.

What is the interaction between DEFB4A and other biomolecules? 02/01/2020

There are interactions between DEFB4A and other biomolecules. For example, it can bind to the cell membrane of pathogenic microorganisms and disrupt their integrity to exert antimicrobial effects, and it can also bind to receptors on the surface of epithelial cells to activate signal transduction pathways and regulate cellular immune responses.
