There are reports demonstrating that after SCI the macrophages response actively and play an important role in the development of secondary injury [ 5- 7].
The results obtained document how the endogenous opioid peptides and the hypophysis-adrenocortical response actively modulate the adaptation to transport stress conditions in horses, albeit in a temporally differentiated way.
However, after identical intravenous infective challenge (bypassing the skin) [128], diminished immunity with high dose skin immunization (compared to intravenous) [128] must derive from deficient host responses (activated less efficiently, or actively depressed, or both), not parasite-intrinsic changes.
Some of these changes may not result solely from host responses, but actively induced changes by parasites/parasitoids to manipulate the host to acquire some benefit (e.g. parasite/parasitoid survivorship or dispersal ability).
We found increased fMRI responses to actively compared with passively learned melodies in the left anterior insula, extending to the left fronto-opercular cortex.
Furthermore, it has been suggested that SARS-CoV and other members of the Group 2 CoVs, such as mouse hepatitis virus (MHV), could effectively evade IFN-related antiviral responses by actively avoiding the recognition of their replicative RNAs by the host innate sensing mechanism/s [33], [34].
We speculate that this de novo steroid production may be an intrinsic phenomenon of Th2-mediated immune responses to actively restore immune homeostasis.
The present study confirmed other researchers' investigation that active sensitization per se induces airway eosinophilic inflammation and increase in cough reflex sensitivity [ 11] and our previous data [ 5] that an aerosolized antigen challenge further enhances the airway responses in actively sensitized animals.
This force configuration is to demonstrate the feasibility of attenuating the plate response by actively modifying the beam response.
In human lung tissue, epithelial cells mediate an initial inflammatory response by actively secreting specific cytokines that recruit and activate inflammatory cells, such as neutrophils or macrophages, 48 or by the release of damage-associated molecular pattern molecules from necrotic cells.
