Crystal structure of exfoliative toxin D from Staphylococcus aureus.
Biochem Biophys Res Commun
November 2024
Article Synopsis
- * This study provides a detailed crystal structure of ETD at 1.75 Å resolution, revealing a composition of two β-barrels and two α-helices, similar to other ET structures.
- * A model suggests that a segment of human desmoglein-1 (IEGP) interacts significantly with ETD, with unique features in the structure of loop D indicating potential variations in ETD's binding capabilities compared to other ETs.
Article Synopsis
- * A 48-year-old woman experienced AIVR during a tooth extraction under general anesthesia after local anesthetic was injected into the oral mucosa, causing temporary changes in her heart rhythm.
- * The AIVR was likely triggered by the trigeminocardiac reflex due to injection-related pain, highlighting the need for careful administration of local anesthetics, especially with larger needles and firm pressure.
Titanium is often used in the medical field and in dental implants due to its biocompatibility, but it has a high rate of leading to peri-implantitis, which progresses faster than periodontitis. Therefore, in the present study, the expression of cytokines from gingival epithelial cells by nanotitania was investigated, which is derived from titanium in the oral cavity, and the additional effect of (periodontopathic bacteria) lipopolysaccharide (PgLPS) was investigated. Ca9-22 cells were used as a gingival epithelial cell model and were cultured with nanotitania alone or with PgLPS.

Analyses of the amino acid sequences of component VII (N-type Hb) and component V (L-type Hb) from P. akamusi indicated that one remarkable difference is the replacement of the distal histidine (His) with isoleucine (Ile) in component V.
