| Summary |
DEFB103B inhibits cell wall biosynthesis in staphylococci by inhibiting those enzymes which use the bactoprenol bound cell wall building block Lipid II as substrate.
DEFB103B exerts anti-inflammatory activities by specifically targeting TLR signalling pathways to transcriptionally repress pro-inflammatory genes.
DEFB103B (hBD-3) is sequestered by extracellular DNA in Haemophilus influenzae biofilms to reduce its antimicrobial activity.
DEFB103B (hBD3) induces dendritic cell activation, migration and polarization in the skin.
DEFB103B (hBD3) is induced in leprosy type 1 reactions in keratinocytes.
Exposure to ambient air pollution particulate matter deregulates the ability of the human type II alveolar epithelial cells (A549) to express the antimicrobial peptides HBD-2 (DEFB4A/DEFB4B) and HBD-3 (DEFB103A/DEFB103B) upon infection with Mycobacterium tuberculosis and increases intracellular M. tuberculosis growth.

| Summary |
Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils. Members of the defensin family are highly similar in protein sequence. This gene encodes defensin, beta 103B, which has broad spectrum antimicrobial activity and may play an important role in innate epithelial defense. [provided by RefSeq, Jul 2008] |
