Infection and Tumor Formation in Chickens By Avian Leukosis Virus
Lymphoid leukosis in chickens is a disease which arises from the result of complicated interaction between avian leukosis virus (ALV) as a pathogenic organism and chicken as a host. This report is intended to outline our present knowledge about genetic resistance of chickens in lymphoid leukosis. The defense of host in infectious disease could be considered dividing it into two: one as a workin...
متن کاملA novel subgroup of exogenous avian leukosis virus in chickens.
An avian leukosis virus with a wide host range belonging to a new subgroup for chickens was isolated from meat-type chicken lines. The virus, of which HPRS-103 strain is the prototype, was of low oncogenicity in chickens but appeared to behave like an exogenous leukosis virus. Neutralizing antibodies to the virus were found in three of five meat-type chicken lines, but not in seven layer lines....
متن کاملAvian Leukosis Virus Subgroup J in Layer Chickens, China
To the Editor: In recent years, cases of avian leukosis virus subgroup J (ALV-J) infection and tumors in commercial layer chickens and breeders of egg-type chickens have been emerging in the People’s Republic of China. ALV-J was fi rst isolated from meattype chickens with myeloid leukosis in 1988. Although egg-type chickens have been experimentally infected with ALV-J to induce tumors (1), fi e...
متن کاملDomestic chickens activate a piRNA defense against avian leukosis virus
PIWI-interacting RNAs (piRNAs) protect the germ line by targeting transposable elements (TEs) through the base-pair complementarity. We do not know how piRNAs co-evolve with TEs in chickens. Here we reported that all active TEs in the chicken germ line are targeted by piRNAs, and as TEs lose their activity, the corresponding piRNAs erode away. We observed de novo piRNA birth as host responds to...
متن کاملCircular RNA alterations are involved in resistance to avian leukosis virus subgroup-J-induced tumor formation in chickens
Avian leukosis virus subgroup (ALV-J) is an oncogenic neoplasm-inducing retrovirus that causes significant economic losses in the poultry industry. Recent studies have demonstrated circular RNAs (circRNAs) are implicated in pathogenic processes; however, no research has indicated circRNAs are involved in resistance to disease. In this study, over 1800 circRNAs were detected by circRNA sequencin...
