چکیده

conclusions this study delineated the beneficial role of rsv for growth regulation of skin cancer cells and highlighted the involvement of rsv in the induction of apoptosis in a431 cells. these findings might conduct evidence into the oncolytic properties of rsv in the skin cancer. further studies are required to indicate intracellular targets for rsv-induced apoptosis in skin cancer cells. results the results indicated that a431 cell growth was inhibited following infection by rsv in a dose- and time-dependent manner. the most growth inhibitory effect of rsv was occurred at the moi of 3, and 48 hour after infection. the inhibitory effect of rsv on the cell growth was accompanied by the induction of apoptosis in the skin cancer cells. the percentages of early and late apoptotic cells were increased following exposure to rsv in a concentration- and time-dependent manner. materials and methods plaque assay was used to determine rsv titers. the cytotoxic effect of rsv in a431 (skin carcinoma cell line) was determined using mtt assay. the detection of apoptosis was performed via annexin-v-fitc staining method and analyzed with flow cytometry. background oncolytic viruses have become of noticeable interest as a novel biological approach for selectively infecting cancer cells and triggering apoptosis in a number of malignant cells. many researches are devoted to characterize more viruses with oncolytic properties. objectives evidences on the oncolytic feature of respiratory syncytial virus (rsv) are conflicting; therefore, this study was designed to elucidate the possible role of rsv on the modulation of cell growth and apoptosis in the skin cancer cells.

Identification of Respiratory Syncytial Virus (RSV) Genome in the Stool of a Child with Acute Gastroenteritis

Case Report: Some viruses have been reported to cause respiratory and gastroenteric infections simultaneously. In this case we present isolation of human respiratory virus (RSV) type B from diarrheal sample of a 12 months' child with acute gastroenteritis. Results: The results indicated the presence of RSV subtype B genome in all three stool samples. Moreover, no sign of co-infections with oth...

What is respiratory syncytial virus (RSV)?

one of the most common causes of bronchiolitis and pneumonia in children under 1 year of age in the United States. It is a common reason for young infants to be hospitalized during the RSV season. RSV can also cause serious respiratory illness in older adults. Most healthy people recover from RSV infection in 1 to 2 weeks. However, infection can be severe in a few, usually among those who are a...

Epidemiological Changes of Respiratory Syncytial Virus (RSV) Infections in Israel

RSV is the leading cause of lower respiratory-tract infections in infants and therefore demands in-depth epidemiological characterization. We investigated here the distribution of RSV types in Israel between the years 2005-2012. Clinical samples were collected from 11,018 patients hospitalized due to respiratory illnesses and were evaluated for the presence of various respiratory viruses, inclu...
