MRL/fas(lpr) mice are affected by a systemic autoimmune disease that results in widespread leukocytic infiltration of the vasculature, including in the skin. The molecular pathways responsible for this leukocyte recruitment are poorly understood. Therefore, the aim of these experiments was to examine the mechanisms of leukocyte trafficking in the dermal microvasculature of MRL/fas(lpr) mice. In...

Ligation of the cell-surface Fas molecule by its ligand (Fas-L) or agonistic anti-Fas monoclonal antibodies results in the cleavage and activation of the cysteine protease procaspase 8 followed by the activation of procaspase 3 and by apoptosis. In some leukemia cell lines, cytotoxic drugs induce expression of Fas-L, which may contribute to cell killing through the ligation of Fas. The involvem...

The biological functions of leptin in the human endometrial epithelium were investigated using the human endometrial epithelial cell line, HHUA. Specifically, the effects of leptin on the proliferation and apoptosis of HHUA cells induced by treatment with anti-Fas IgM or anticancer drugs were examined. RT-PCR detected the expression of four leptin receptor isoform mRNAs in the cells and flow cy...

Face anti-spoofing (FAS) plays a vital role in securing face recognition systems. Existing methods heavily rely on the expert-designed networks, which may lead to sub-optimal solution for FAS task. Here we propose first method based neural architecture search (NAS), called NAS-FAS, discover well-suited task-aware networks. Unlike previous NAS works mainly focus developing efficient strategies g...

MRL/MpJ-Tnfrsf6(lpr) (MRL/MpJ-Fas(lpr); MRL-Fas(lpr)) mice develop a spontaneous lupus syndrome closely resembling human systemic lupus erythematosus. To define the role of IL-10 in the regulation of murine lupus, IL-10 gene-deficient (IL-10(-/-)) MRL-Fas(lpr) (MRL-Fas(lpr) IL-10(-/-)) mice were generated and their disease phenotype was compared with littermates with one or two copies of an int...

To find out which cytokines are involved in the pathogenesis of multiple myeloma, we investigated cytokine receptor expression on myeloma cells using a panel of monoclonal antibodies (MoAbs). Flow cytometric analysis of five myeloma cell lines (RPMI8226, ARH77, KMM-1, U266, and Hs) and myeloma cells freshly isolated from eight patients showed that interleukin-1 receptor (IL-1R) type I and type ...

We previously observed the presence of anti-human mu-opioid-receptor (anti-hMOR) autoantibodies in IgG pools prepared from several thousand healthy blood donors. These autoantibodies behaved agonistically because of their ability to bind to the first and third extracellular loops of the receptor. In this study, we found that each healthy donor's serum contained anti-hMOR IgG autoantibodies with...

We have previously engineered new RNase P-based ribozyme variants with improved in vitro catalytic activity. In this study, we employed a novel engineered variant to target a shared mRNA region of human cytomegalovirus (HCMV) immediate early proteins 1 (IE1) and 2 (IE2), which are essential for the expression of viral early and late genes as well as viral growth. Ribozyme F-R228-IE represents a...

BACKGROUND We previously reported that Fas antigen was strongly expressed on salivary duct epithelial cells and that some salivary infiltrating cells showed the Fas ligand in patients with severe sialoadenitis due to Sjögren's syndrome (SS). Apoptotic changes were observed in ductal epithelial cells and some infiltrating cells by DNA nick end labeling methods. These findings suggest that the Fa...
