If they lack corresponding disease resistance proteins, avirulence products can function as virulence factors, subverting host cellular functions through interactions with plant-encoded pathogenicity targets [ 44].
Thus, tumor-derived secreted factors subvert the normal pattern of myeloid cell-driven inflammation.
These factors subvert normal host cell functions in ways that seem beneficial to invading bacteria.
The latter indicates that edited tumor cells may continue to express relevant target antigens that can be functionally unmasked upon removal of tumor-derived suppressive factors that subvert myeloid cell, including DC, function.
Viral adaptations can reduce the binding affinity of the peptide to the HLA molecule and result in poor peptide cleavage or poor T cell recognition; these factors can subvert host immune control (reviewed by Bowden and Walker 12).
Previous kinetic data show that the in vitro assembly of the 30S subunit often encounters kinetic traps in the 3′ domain, such as those caused by prior binding of late proteins, and predicts that assembly factors function to subvert these kinetic traps (Bunner et al., 2010; Mulder et al., 2010; Talkington et al., 2005).
Found in many plant and animal pathogens, T3SSs function to deliver bacterial virulence factors that typically subvert host defenses and/or manipulate host processes, such as cytoskeletal rearrangements (Galan and Collmer, 1999).
Defects in programmed cell death (apoptosis) mechanisms play important roles in tumor pathogenesis, allowing neoplastic cells to survive over intended lifespans, subverting the need for exogenous survival factors and providing protection from oxidative stress and hypoxia as the tumor mass expands.
As their growth hidden from immune recognition is not enough to allay their obsession with attacks on the part of the immune system, most all?—tumors acquire the ability to release a series of factors and cytokines to subvert normal reaction mechanisms.
In A. phagocytophilum, which preferentially colonize neutrophilic white blood cells, it is thought that the T4SS secretes virulence factors that are responsible for subverting innate immunity and inhibiting host cell apoptosis [ 16].
