Group C adenovirus DNA sequences in human lymphoid cells. 1986

J Horvath, and L Palkonyay, and J Weber

Human peripheral blood lymphocytes from healthy adults, cord blood lymphocytes, and lymphoblastoid cell lines were screened by hybridization for the presence of group C adenovirus DNA sequences. In 13 of 17 peripheral blood lymphocyte samples from adults, 1 of 10 cord blood samples, and seven of seven lymphoblastoid cell lines tested, results were positive for Group C adenovirus DNA (adenovirus 1 [Ad1], Ad2, Ad5, or Ad6). About 1 to 2% of the lymphocytes carried 50 to 100 viral genome copies per positive cell, as estimated by in situ hybridization. Infectious virus representing all members of group C were recovered, but cultivation in the presence of adenovirus antibody did not cure the cells of free viral genomes. Viral DNA was found in B, T, and N cells but only in 1 of 10 cord blood samples. The results suggest that group C adenovirus infections in childhood result in the persistence of the viral genome in circulating lymphocytes.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D005312	Fetal Blood	Blood of the fetus. Exchange of nutrients and waste between the fetal and maternal blood occurs via the PLACENTA. The cord blood is blood contained in the umbilical vessels (UMBILICAL CORD) at the time of delivery.

D000260	Adenoviruses, Human	Species of the genus MASTADENOVIRUS, causing a wide range of diseases in humans. Infections are mostly asymptomatic, but can be associated with diseases of the respiratory, ocular, and gastrointestinal systems. Serotypes (named with Arabic numbers) have been grouped into species designated Human adenovirus A-G.	APC Viruses,APC Virus,Adenovirus, Human,Human Adenovirus,Human Adenoviruses
D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
