Pa-Fan Hsiao, Yu-Hung Wu
BACKGROUND/AIMS: Cutaneous plasmacytosis is rare and still not well understood. A retrospective study was made of 9 Chinese patients with 1- to 15-year histories of biopsy-proven cutaneous plasmacytosis diagnosed between 2003 and 2015. METHODS: Patient records and archival photographs helped establish the pattern and duration of skin lesions, and skin biopsy specimens provided additional data. RESULTS: The mean age at diagnosis was 46.4 years...

Pathogenic autoantibodies associated with neuromyelitis optica (NMO) induce disease by targeting aquaporin-4 (AQP4) water channels enriched on astrocytic endfeet at blood-brain interfaces. AQP4 is also expressed at cerebrospinal fluid (CSF)-brain interfaces, such as the pial glia limitans and the ependyma and at the choroid plexus blood-CSF barrier. However, little is known regarding pathology at these sites in NMO. Therefore, we evaluated AQP4 expression, microglial reactivity, and complement deposition at pial and ependymal surfaces and in the fourth ventricle choroid plexus in 23 autopsy cases with clinically and/or pathologically confirmed NMO or NMO spectrum disorder...

Annexin II on mesangial cell surface mediates the binding of anti-dsDNA antibodies and consequent downstream inflammatory and fibrotic processes. We investigated the clinical relevance of circulating annexin II-binding immunoglobulins in patients with severe proliferative lupus nephritis, and renal annexin II expression in relation to progression of nephritis in NZBWF1/J mice. Annexin II-binding immunoglobulins in serum were measured by ELISA. Ultrastructural localization of annexin II was determined by electron microscopy...

The HLA-A11 or -A33 allele is found in approximately 18% or 10% of the Asian population, respectively, but each of which is a minor allele worldwide, and therefore no clinical trials were previously conducted. To develop a therapeutic peptide vaccine for each of them, we investigated immunological responses of advanced cancer patients with the HLA-A11(+) /A11(+) (n=18) or -A33(+) /A33(+) (n=13) allele to personalized peptide vaccine (PPV) regimens. The primary sites of HLA-A11+/A11+ or -A33+/A33+ patients were the colon (n=4 or 2), stomach (2 or 3), breast (3 or 2), lung and pancreas(2 or 2), and so on...

BACKGROUND: Currently, no vaccine against Pseudomonas is available. IC43 is a new, recombinant, protein (OprF/I)-based vaccine against the opportunistic pathogen, Pseudomonas aeruginosa, a major cause of serious hospital-acquired infections. IC43 has proven immunogenicity and tolerability in healthy volunteers, patients with burns, and patients with chronic lung diseases. In order to assess the immunogenicity and safety of IC43 in patients who are most at risk of acquiring Pseudomonas infections, it was evaluated in mechanically ventilated ICU patients...

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic inflammatory disease that has protean manifestations and follows a relapsing and remitting course. More than 90% of cases of SLE occur in women, frequently starting at childbearing age. It is characterized by the presence of autoantibodies potentially directed toward every organ or apparatus. Cardiac alterations are frequent in patients affected by SLE and the simultaneous presence of antiphospholipid antibodies (aPL), able to cause arterial thrombosis in any vascular district, is considered a possible risk factor for cardiac damage in SLE patients...

BACKGROUND: Salmonella Typhimurium (S. Typhimurium) inactivated by a regulated autolysis system was genetically engineered to express the homo-pentameric B subunit of Shiga toxin 2e (Stx2eB) on its surface. To prepare a strain able to yield autolyzed Salmonella bearing Stx2eB, the plasmid pJHL184 harboring stx 2eB gene was transformed into the attenuated S. Typhimurium strain, JOL1454. Stx2eB subcloned into the antigen delivery cassette of the plasmid was expressed as fusion protein with the outer membrane protein RESULTS: The expression of Stx2eB fused to the signal peptide in JOL1454 was validated by immunoblot analysis...

Severe lupus often includes psychiatric and neurological sequelae, although the cellular contributors to CNS disease remain poorly defined. Using intravascular staining to discriminate tissue-localized from blood-borne cells, we find substantial accumulation of CD8(+) T cells relative to other lymphocytes in brain tissue, which correlates with lupus disease and limited neuropathology. This is in contrast to all other affected organs, where infiltrating CD4(+) cells are predominant. Brain-infiltrating CD8(+) T cells represent an activated subset of those found in the periphery, having a resident-memory phenotype (CD69(+)CD122(-)PD1(+)CD44(+)CD62L(-)) and expressing adhesion molecules (VLA-4(+)LFA-1(+)) complementary to activated brain endothelium...

A 13-year-old, castrated male Maine Coon cat was presented to Oklahoma State University Boren Veterinary Medical Teaching Hospital for yearly echocardiographic examination monitoring hypertrophic cardiomyopathy (HCM) diagnosed in 2003. Physical examination revealed a heart murmur and premature beats, likely related to HCM, but was otherwise unremarkable. A biochemistry profile revealed a hyperglobulinemia (6.3 g/dL). Cytologic examination of fine-needle aspirates from liver and spleen revealed increased numbers of plasma cells and mast cells, confirmed with subsequent histologic examination...

PURPOSE: Vulnerable plaques are key factors for ischemic diseases. Thus, their precise detection is necessary for the diagnosis of such diseases. Immunoglobulin G (IgG)-based imaging probes have been developed for imaging biomolecules related to plaque formation for the diagnosis of atherosclerosis. However, IgG accumulates nonspecifically in atherosclerotic regions, and its accumulation mechanisms have not yet been clarified in detail. Therefore, we explored IgG accumulation mechanisms in atherosclerotic lesions and examined images of radiolabeled IgG for the diagnosis of atherosclerosis...
