SUMMARY We investigated cytokine profiles in interleukin (IL)-4 transgenic (Tg) mice with a skin inflammatory disease resembling human atopic dermatitis. cDNA microarray revealed that the mRNAs encoding IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12p40, IL-13, tumour necrosis factor (TNF)-α, TNF-β and interferon (IFN)-γ were up-regulated of late lesion Tg to lesser degree non-lesion when compared those non-Tg mice. Real time reverse transcription–polymerase chain reaction (RT-PCR)...

IL-1 may influence or be influenced by a number of abnormalities present in psoriasis; including keratinocyte proliferation, eicosanoid production, fibroblast activation, endothelial cell adhesiveness, T infiltration and cyclic nucleotide metabolism, transmembrane signal transduction mechanisms. We assessed regulation normal, uninvolved, involved skin psoriatic patients using immunofluorescence microscopy, sensitive ELISA method to quantitate immunoreactive beta alpha protein levels, the...

The objective of these studies was to characterize the IL-1 inhibitory activity present in normal and psoriatic epidermis from clinically stable lesions. Fractionation epidermal cytosol on a molecular sizing column failed reveal presence bioactivity. However, specific ELISAs indicated that both receptor antagonist (IL-1ra) alpha were overlapping peaks. Further fractionation by anion exchange chromatography separated two molecules, revealing bioactivity IL-1ra molecule. Similar protein....

ABSTRACT We present the largest optical photometry compilation of gamma-ray bursts (GRBs) with redshifts (z). include 64813 observations 535 events (including upper limits) from 28 February 1997 to 18 August 2023. also a user-friendly web tool grbLC which allows users visualize photometry, coordinates, redshift, host galaxy extinction, and spectral indices for each event in our database. Furthermore, we have added Gamma-ray Coordinate Network (GCN) scraper that can be used collect data by...

Bullous systemic lupus erythematosus is a generalized subepidermal blistering skin eruption in patients suffering from erythematosus. Type VII collagen was initially identified as the target antigen.We studied an unusual patient who had bullous crythematosus. The fulfilled criteria of with antinuclear antibody titer 1:5120. Immunopathological testing revealed vivo deposition all IgG subclasses, secretory IgA1, and both light chains at patient's basement membrane. vivo-bound IgA were...

We characterized basement membrane zone (BMZ) autoantigens targeted by autoantibodies (AAb) from patients with cicatricial pemphigoid. Serum a patient severe oral pemphigoid contained IgG anti-BMZ AAb. The AAb labeled lower BMZ component on salt-split skin and localized to the lamina lucida/lamina densa direct indirect immunoelectron microscopy (IEM) but did not label blood vessels. react EHS laminin-1 type IV collagen, pepsinized human recombinant entactin, or NC1 domain of VII collagen dot...

<h3>• Background and Design.—</h3> There is much confusion in the clinical classification of immune-mediated subepithelial blistering diseases mucous membranes. We conducted a 6-year comprehensive study to better classify this heterogeneous disease group. Indirect immunofluorescence was performed on salt-split-skin substrate detect circulating antibasement membrane antibodies (n=47). Serologic reactivity against cultured keratinocyte antigens examined by immunoblots (n=38)...
