Glomerular Lesions

Mice of the inbred NZB strain develop a spontaneous disease characterized by autoimmune hemolytic anemia, positive lupus erythematosus cell tests and antinuclear antibodies and nephritis. This disease is analogous to human systemic lupus erythematosus. In ultrastructural studies of the glomerular lesion in NZB mice, intraglomerular dense deposits in mesangial, subepithelial and subendothelial locations were described. In common with the findings in many examples of human and experimental nephritis, including many cases of human lupus nephritis, these deposits were amorphous or slightly granular in appearance with no definable substructure.We have recently observed structured deposits in the glomeruli of NZB mice. They were uncommon and were found in older animals with severe glomerular lesions by morphologic criteria. They were seen most commonly as extracellular elements in subendothelial and mesangial regions. The deposits ranged up to 3 microns in greatest dimension and were often adjacent to deposits of lipid-like round particles of 30 to 250 millimicrons in diameter and with amorphous dense deposits.

Aims: The present study was conducted to examine the inhibitory effects of synthesized sulfonylhydrazones on the expression of CD73 (ecto-5′-NT). Background: CD73 (ecto-5′-NT) represents the most significant class of ecto-nucleotidases which are mainly responsible for dephosphorylation of adenosine monophosphate to adenosine. Inhibition of CD73 played an important role in the treatment of cancer, autoimmune disorders, precancerous syndromes, and some other diseases associated with CD73 activity. Objective: Keeping in view the significance of CD73 inhibitor in the treatment of cervical cancer, a series of sulfonylhydrazones (3a-3i) derivatives synthesized from 3-formylchromones were evaluated. Methods: All sulfonylhydrazones (3a-3i) were evaluated for their inhibitory activity towards CD73 (ecto-5′-NT) by the malachite green assay and their cytotoxic effect was investigated on HeLa cell line using MTT assay. Secondly, most potent compound was selected for cell apoptosis, immunofluorescence staining and cell cycle analysis. After that, CD73 mRNA and protein expression were analyzed by real-time PCR and Western blot. Results: Among all compounds, 3h, 3e, 3b, and 3c were found the most active against rat-ecto-5′-NT (CD73) enzyme with IC50 (µM) values of 0.70 ± 0.06 µM, 0.87 ± 0.05 µM, 0.39 ± 0.02 µM and 0.33 ± 0.03 µM, respectively. These derivatives were further evaluated for their cytotoxic potential against cancer cell line (HeLa). Compound 3h and 3c showed the cytotoxicity at IC50 value of 30.20 ± 3.11 µM and 86.02 ± 7.11 µM, respectively. Furthermore, compound 3h was selected for cell apoptosis, immunofluorescence staining and cell cycle analysis which showed promising apoptotic effect in HeLa cells. Additionally, compound 3h was further investigated for its effect on expression of CD73 using qRT-PCR and western blot. Conclusion: Among all synthesized compounds (3a-3i), Compound 3h (E)-N'-((6-ethyl-4-oxo-4H-chromen-3-yl) methylene)-4-methylbenzenesulfonohydrazide was identified as most potent compound. Additional expression studies conducted on HeLa cell line proved that this compound successfully decreased the expression level of CD73 and thus inhibiting the growth and proliferation of cancer cells.

Abstract Autoimmune diseases are pathological conditions in which the immune system mistakenly attacks its own tissues. This study evaluates the performance of two techniques, which are identifiers of autoantibody specifics: immunoblot and immunodot. This study was conducted in 300 patients of whom 62 were tested positive for antinuclear antibodies. The patients were initially screened for antinuclear antibodies using indirect immunofluorescence. Then, the identification of specific autoantibodies such as anti-extractable nuclear antigens (ENAs) was carried out using the immunoblot and immunodot techniques. The results showed that immunoblot and immunodot did not present a significant difference in their sensitivity against anti-SSA/52, SSB, CENP-B, PCNA, U1-snRNP, Jo-1, Pm-scl, and Mi-2 (p > 0.05). However, the two techniques showed a significant difference in their sensitivity toward autoantibodies anti-DNAn, anti-histone, anti-SmD1, and anti-ds-DNA (p < 0.05). The immunoblot data were in complete accordance with the immunodot data (100%) regarding the detection of autoantibodies such as anti SSA/52, SSB, CENP-B, PCNA, U1-snRP, Jo-1, Pm-scl, and Mi-2, 80% regarding SmD1, and 75% concerning ds-DNA. We should certainly pay closer attention to the efficiency of the techniques used in the diagnosis of autoimmune diseases.
