HELPER-DEPENDENT VECTOR TRANSMISSION OF PLANT VIRUSES
Annual Review of Phytopathology, 1996▪ Abstract A variety of noncirculatively transmitted viruses have evolved a vector transmission strategy that involves, in addition to virions, virus-encoded proteins that are not constituents of virions. These “helpers” and the genes encoding them have been characterized for viruses in the genera Potyvirus and Caulimovirus.

Biology and structure of plant satellite viruses activated by icosahedral helper viruses.
Current Topics in Microbiology and Immunology, 1999Nearly 40 years ago, Kassanis and Nixon (1960) described two kinds of particles in tobacco necrosis virus (TNV) infections that differed in size, and thus seemed to be separate viruses. The smaller component was demonstrated to depend on the larger autonomous virus for its multiplication, and hence was designated a satellite virus, satellite tobacco ...

Helper viruses associated with avian acute leukemia viruses inhibit the cellular immune response.
Virology, 1982Abstract The cellular immune competence of lymphocytes obtained from birds infected with acute or chronic leukemia viruses was studied. The in vitro blastogenic response of thymus-derived lymphocytes (T cells) to the mitogens phytohemagglutinin (PHA) and connanavalin A (Con A) correlates with the ability of birds to elicit a cellular immune ...

Studies on Induction of Virus from Adenovirus and SV40 Hamster Tumors 2. “Helper” Viruses.∗
Experimental Biology and Medicine, 1966 SummaryCell culture lines of virus-free hamster tumors which were initiated by ade-novirus 7 (Pinckney and Grider) or by adenovirus 18 and which synthesized “T” antigen were tested exhaustively for release of infectious adenovirus following addition of candidate “helper” viruses including SV40 respiratory syncytial virus and reovirus type 1.

Viral Immunology, 2017
The lung is an important line of defense that is exposed to respiratory infectious pathogens, including viruses. Lung epithelial cells and/or alveolar macrophages are initially targeted by respiratory viruses. Once respiratory viruses invade the cells of the lung, innate immunity is activated to inhibit viral replication.

Specificity of the helper T cell for the cytolytic T lymphocyte response to influenza viruses [PDF]
Journal of Experimental Medicine, 1981 We have described a model system in which helper T cells are required to mount a primary antiviral cytolytic T lymphocyte response. The radioresistant helper cell can be found in the spleens of mice that have been immunized subcutaneously with influenza viruses 6-8 d previously. These helper cells appear to be type specific but cross-reactive among the

Viral MIRNAS: Tiny but Mighty Helpers for Large and Small DNA Viruses
Future Virology, 2008Recognition of the importance of noncoding RNAs has risen exponentially since the discovery that small molecules of 20–26 nucleotides in length were at the core of all RNA silencing phenomena. Among those small RNAs, miRNAs clearly represent the most prominent family and have been implicated in a wide range of biological processes.
