Why HeLa cells do not produce interferon? 1977

Z Blach-Olszewska, and J Halasa, and H Matej, and M Cembrzyńska-Nowak

The investigation was carried out with HeLa cells which were not sensitive to antiviral action of human diploid cell interferon and do not produce interferon after induction with Newcastle disease virus. Identity of this line was confirmed by determination of stable genetic markers such as isoenzymes and histocompatibility antigens. On electrophoresis of lysed HeLa cells the following human red cell enzymes phenotypes were found: PGM (1-1), AP, EsD, and GTP. It was shown that on the surface of HeLa cells membranes HLA antigens are expressed: A28, BW35, A3. The results are in agreement with those which were obtained from Henrietta Lack's family study. Chromosome G-banding analysis revealed disproportion between the number of chromosomes connected with production and action of interferon and chromosomes which are supposed to control these processes.

UI	MeSH Term	Description	Entries
D007125	Immunogenetics	A subdiscipline of genetics which deals with the genetic basis of the immune response (IMMUNITY).	Immunogenetic
D007372	Interferons	Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions.	Interferon

D009522	Newcastle disease virus	The most well known avian paramyxovirus in the genus AVULAVIRUS and the cause of a highly infectious pneumoencephalitis in fowl. It is also reported to cause CONJUNCTIVITIS in humans. Transmission is by droplet inhalation or ingestion of contaminated water or food.	Avian Paramyxovirus 1,Paramyxovirus 1, Avian
D004912	Erythrocytes	Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.

D006367	HeLa Cells	The first continuously cultured human malignant CELL LINE, derived from the cervical carcinoma of Henrietta Lacks. These cells are used for, among other things, VIRUS CULTIVATION and PRECLINICAL DRUG EVALUATION assays.	Cell, HeLa,Cells, HeLa,HeLa Cell
D006680	HLA Antigens	Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans. They are polypeptides or glycoproteins found on most nucleated cells and platelets, determine tissue types for transplantation, and are associated with certain diseases.
