Viral infection of the liver can lead to severe tissue damage when high levels of viral replication and spread in the organ are coupled with strong induction of inflammatory responses. Here we report an unexpected correlation between the expression of a functional X domain encoded by the
Rubella virus (RV) infections in adult women can be associated with acute and chronic arthritic symptoms. In many autoimmune individuals, antibodies are found targeting endogenous proteins, called autoantigens, contained in ribonucleoprotein complexes (RNPs). In order to understand the molecular
The rubella virus (RV)-encoded protein NSP90, which contains the retinoblastoma protein (Rb)-binding motif LXCXE, interacts with Rb and RV replication is reduced in cells lacking Rb. Whether the LXCXE motif of RV NSP90 itself is essential for Rb binding and virus replication is not known. Therefore,
Rubella virus is an enveloped positive-strand RNA virus of the family TOGAVIRIDAE: Virions are composed of three structural proteins: a capsid and two membrane-spanning glycoproteins, E2 and E1. During virus assembly, the capsid interacts with genomic RNA to form nucleocapsids. In the present study,
We previously demonstrated that human embryonic mesenchymal cells derived from the palate (HEMP cells) retain alkaline phosphatase (ALP) content and capacity for collagen synthesis after long-term culture, and their growth is markedly stimulated by epidermal growth factor (EGF). There was a dramatic
Previously, we observed that sequences at the 3' end of rubella virus (RV) genomic RNA that form a stable stem-loop structure are necessary for initiation of RNA replication. A cytosolic protein found in Vero 76 cells (simian origin) specifically bound to the 3' (+)-stem-loop sequence. In the
Replication of rubella virus is initiated at the 3' end of the genomic RNA. An inverted repeat sequence of 12 nucleotides that is capable of forming a stem-loop structure is located at the 3' end of the RNA, 59 nucleotides upstream from the poly (A) tail. We screened the 158-bp region of the 3' end
The fully automated IMx immunoassay analyzer was used to develop a system for the detection of IgG and IgM antibodies to rubella virus for immune status screening and diagnosis of primary infections. Reagents and assay protocol software were developed using rubella virus sensitized microparticles as
Enzyme-immunoassays using an indirect method with alkaline phosphatase conjugated antiglobulins were satisfactory for detection of antibody to Measles and Cytomegalovirus. The antigen was passively adsorbed to polystyrene micro-harmagglutination plates for the assays. IgM antibody to Rubella was
The congenital rubella syndrome (CRS) is associated with increased risk for diabetes and thyroid disease. However, the mechanisms by which the rubella virus may cause these diseases are poorly characterized. Previous studies were carried out before modern immunological methods were available. The
Replication complexes are membrane-bound cytoplasmic vacuoles involved in rubella virus (RV) replication. These structures can be identified by their characteristic morphology at the electron microscopy (EM) level and by their association with double-stranded (ds) RNA in immunogold labeling EM
Genetic polymorphisms are known to affect responses to both viral infection and vaccination. Our previous work has described genetic polymorphisms significantly associated with variations in immune response to rubella vaccine from multiple gene families with known immune function, including HLA,
We studied the role of autochthonous microflora from body cavities in the development of tissue hypoxia and instability of cell membranes. In children with tuberculosis dysbiosis manifested in nonspecific quantitative changes in the intestinal microflora and the presence of coxsackievirus antigens
We studied a case of Fahr's disease type idiopathic intracerebral calcification (Fahr's disease) associated with juvenile rheumatoid arthritis. The patient was a 15-year-old male with a chief complaint of gait disturbance. His family members had no similar signs and symptoms. His parents had no
The immobilization of purified influenza virus, rubella virus, crude nuclear cytomegalovirus antigen and of mycoplasma on polystyrene tubes was studied using radio-iodinated preparations. The antigen activities on tube surfaces were determined using sequentially specific human antibodies and
