To analyse the endocytic mechanism responsible for EV internalization, and to test whether endocytosis was required for infection by intact EVs, we infected HeLa cells in the presence of a spectrum of small compound inhibitors known to affect endocytic processes.
Despite the mechanisms of resistance to the complement system, the differences of T. cruzi strains and the high parasite load required for infection suggest that not all metacyclic trypomastigotes succeed in infecting the host [12], [28], [29], [30], [31].
Since zoospores do not infect leaves right away after inoculation, the time required for infection was also determined for estimation of time needed for development of resistance.
MARCH8 is required for infection with HCV, dengue, and Zika viruses and specifically mediates HCV envelopment.
Noroviruses are the major cause of global viral gastroenteritis with short incubation times and small inoculums required for infection.
The life cycle of the malaria parasite Plasmodium falciparum involves dramatic morphological and molecular changes required for infection of insect and mammalian hosts.
Identifying host targets required for infection that prevents extracellular virus formation such as the GARP complex or the retrograde pathway can provide a potential target for anti-viral therapy.
These strategies include targeting both cellular factors required for infection by various viruses, intracellular bacteria, and/or protozoa as well as factors that modulate the host immune response to these microbial infections.
After discovering how proteins cause viral membranes to fuse with cells, a process required for infection by many viruses, Kim designed molecules that stop membrane fusion by HIV and pioneered efforts to develop vaccines based on similar principles.
T4SS (Type IV Secretion System) is an important virulent factor of Brucella and required for infection suggesting their expression in vivo and can be targeted as serological marker for infection.
Together these results indicated that (i) all viruses replicate similarly in cell culture, (ii) the WT and variant forms of the IFNα/βBPs are not required for infection in cell culture, and (iii) the IFNα/βBPGAGmut versions are correctly synthesised by the engineered viruses during infection.
