OmpA_C‐Like Domain of PorE Is Essential for PorE Function in the Type IX Secretion System (T9SS) of Porphyromonas gingivalis and Some T9SS Cargo Proteins Are Secreted in a PorE‐Independent Manner

Microbiology and Immunology, Volume 70, Issue 1, Page 15-26, January 2026.
ABSTRACT The periodontal pathogen Porphyromonas gingivalis secretes gingipains, highly hydrolytic proteases, to the cell surface or external environment via a type IX secretion system (T9SS). PorE is one of the T9SS component proteins essential for gingipain secretion. It consists of four domains: TPR, WD40, CRD, and OmpA_C‐like.

Recent Advances in Lateral Flow Immunoassay for Rapid Diagnosis of Viral Diseases

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Viral diseases are a major threat to human and animal health, as illustrated by recent pandemics like COVID‐19 and African swine fever (ASF). Timely, accurate detection of viral infections is critical for effective disease control. Among diverse diagnostic techniques, lateral flow immunoassay (LFIA) has become a widely used on‐site testing tool, owing ...

RETROCELL HIV-1 Passive Hemagglutination Assay for HIV-1 Antibody Screening

JAIDS Journal of Acquired Immune Deficiency Syndromes, 1990
A passive hemagglutination assay (PHA) for serum human immunodeficiency virus type 1 (HIV-1) antibody screening was developed using aldehyde-stabilized human erythrocytes coated with purified HIV-1 antigens. The assay is simple to perform, and the components are inexpensive.
