Stepwise molecular-genetic examination in aborted fetuses.

Objective: The evaluation of quantitative fluorescence PCR (QF-PCR) and single nucleotide polymorphism array (SNP array) analysis for the identification of chromosomal abnormalities in products of conception (POC).

Materials And Methods: A total of 1,094 POC samples were processed at Gennet in the years 2018-2020. Chromosomal aneuploidies were tested by QF-PCR using a Omnibor set (STR markers 13, 18, 21, X a Y), SAB-I set (STR markers 2, 7, 15, 16, 22), SAB-II set (from November 2019, STR markers 4, 6, 14) followed by SNP array analysis (Illumina) on samples with a negative QF-PCR result.

Autosomal recessive hereditary spastic paraplegia type SPG35 due to a novel variant in the FA2H gene in a Czech patient.

Biallelic pathogenic variants in FA2H gene have been repeatedly described as a cause of hereditary spastic paraplegia (HSP) type35 (SPG35). Targeted massive parallel sequencing (MPS) of the HSP genes panel revealed a novel homozygous variant c.130C > T (p.

Antisense oligonucleotide ISIS 2922 targets IE-expression and prevents HCMV-IE-induced suppression of TSP-1 and TSP-2 expression.

ISIS 2922, but not ganciclovir (GCV), inhibits HCMV immediate early protein (IE) expression in different infected cell lines and prevents down-modulation of extracellular matrix proteins thrombospondin-1 and -2 induced by IE proteins. While action of ISIS 2922 is mainly due to specific inhibition of IE 2 mRNA, there is also evidence for unspecific effects in terms of inhibition of virus adhesion and penetration.

Decreased neutrophil adhesion to human cytomegalovirus-infected retinal pigment epithelial cells is mediated by virus-induced up-regulation of Fas ligand independent of neutrophil apoptosis.

Human CMV (HCMV) retinitis frequently leads to blindness in iatrogenically immunosuppressed patients and in the end stage of AIDS. Despite the general proinflammatory potential of HCMV, virus infection is associated with a rather mild cellular inflammatory response in the retina. To investigate this phenomenon, the influence of HCMV (strains AD169 or Hi91) infection on C-X-C chemokine secretion, ICAM-1 expression, and neutrophil recruitment in cultured human retinal pigment epithelial (RPE) cells was studied.

Cytomegalovirus infection decreases expression of thrombospondin-1 and -2 in cultured human retinal glial cells: effects of antiviral agents.

In fibroblasts, infection with human cytomegalovirus (HCMV) inhibits expression of the extracellular matrix proteins thrombospondin-1 and -2 (TSP-1 and TSP-2). These effects may depend on expression of HCMV immediate-early (IE) genes, which are activated by cellular transcription factor NF-kappaB. The influence of HCMV infection on TSP-1 and TSP-2 expression and the ability of different antiviral drugs to prevent these cellular changes in permissive cultures of human retinal glial cells were observed.
