Apparent haemocytic transformations associated with parasitoid-induced inhibition of immunity in Malacosoma disstria larvae
Donald B. Stoltz,D. Guzo +1 more
TLDR
It was observed that haemolymph from parasitized larvae does not melanize in vitro; this phenomenon may be associated with a greatly increased stability of oencytoids.About:

Immunological Basis for Compatibility in Parasitoid-Host Relationships
Michael R. Strand,Louis L. Pech +1 more
TL;DR: The insect immune system serves as a key defense against attack by parasitoids, which has likely played a critical role in evolution of host range and in defining parasitoid-host compatibility.
Journal ArticleDOI
How parasitoids deal with the immune system of their host: An overview
TL;DR: The current understanding of insect immunity is reviewed as background to examining the ways in which insect parasitoids have evolved to successfully handle the immune system of the host.
Journal ArticleDOI
Polydnaviruses: potent mediators of host insect immune dysfunction.
M.D. Lavine,N.E. Beckage +1 more
TL;DR: The current evidence for mechanisms of virally induced host immunosuppression in parasitized insects, as well as the roles of other factors including wasp ovarian proteins and venom components, in suppressing hemocyte-mediated and humoral immune responses are summarized.
Journal ArticleDOI
Changes in differential haemocyte count and in vitro behaviour of plasmatocytes from host Heliothis virescens caused by Campoletis sonorensis polydnavirus
TL;DR: The abnormalities induced in H. virescens plasmatocytes by C. sonorensis virus contribute to the suppression of encapsulation, and the onset of haemocytic abnormalities occurred more rapidly after natural parasitism of 3rd-instar host larvae.
Journal ArticleDOI
Modulation of immune responses to parasitoids by polydnaviruses.
TL;DR: Polydnaviruses are powerful influences on the hostimmune system, which serve to permit successful development of the parasitoid without triggering the host immune response.

Plaque formation and isolation of pure lines with poliomyelitis viruses.
Renato Dulbecco,Marguerite Vogt +1 more
TL;DR: Pure virus lines were established by isolating the virus population produced in single plaques, which had the same morphological, serological, and pathogenic properties as the parent strain.

Genetic control of the cell division cycle in yeast: II. Genes controlling DNA replication and its initiation☆☆☆
TL;DR: Temperature-sensitive mutations occurring in two unlinked complementation groups, cdc4 and cdc8, are recessive and result in a defect in DNA replication at the restrictive temperature.
Journal ArticleDOI
Virus in a parasitoid wasp: suppression of the cellular immune response in the parasitoid's host.
TL;DR: A virus that replicates in the ovary of a parasitoids wasp is injected into the parasitoid's host during oviposition, which acts to suppress the host's immune response toward the egg.

Viruses and Parasitism in Insects
Donald B. Stoltz,S.B. Vinson +1 more
TL;DR: It is now apparent that the presence of virus particles in the ovaries of parasitoid wasps is not an isolatcd phenomenon, and may represent the rule rather than the exception among certain groups of endoparasitic hymenoptera.

Induction of degranulation and lysis of haemocytes in the freshwater crayfish, Astacus astacus by components of the prophenoloxidase activating system in vitro.
Valerie Smith,Kenneth Söderhäll +1 more
TL;DR: It is suggested that the attaching proteins of the prophenoloxidase cascade are strong nonself signals for the haemocytes, causing them to degranulate and release previously cell-bound recognition factors into the ha Hemolymph, where they are free to trigger activation of adjacent haemocyte populations.
