059 The psoriasis-associated Act1(D10N) variant reduces keratinocyte and fibroblast responses to IL17 but enhances Th17 responses to polyclonal activation

The responses of horses to predator stimuli

It is not known whether the instincts of wild horses have remained strong during their centuries of domestication. Knowledge of this matter would give riders the opportunity to know more about the behavior of horses and consequently about safety for both horses and riders. In this current research, we studied the behavior of fifteen Caspian miniature horses of different ages and sexes using sti...

Malnutrition enhances cardiovascular responses to chemoreflex activation in awake rats.

Several studies in the literature suggest that low-protein intake is associated with increases in sympathetic efferent activity and cardiovascular disease. Among the possible mechanisms, changes in the neurotransmission of cardiovascular reflexes have been implicated. Therefore, the present study comprised the evaluation of chemoreflex responsiveness in rats subjected to a low-protein diet duri...

Keratinocyte Inflammatory Responses

Keratinocyte proinflammatory responses to adherent and nonadherent group A streptococci.

The gram-positive bacterium Streptococcus pyogenes (group A streptococcus) is the causative agent of a wide variety of suppurative infections of cutaneous tissues. Previous analyses have demonstrated that the M protein of S. pyogenes is an adhesin that directs the attachment of the streptococcus to keratinocytes in the skin. In this study, we have examined keratinocyte function in response to S...

TLR7 Engagement on Dendritic Cells Enhances Autoreactive Th17 Responses via Activation of ERK.

In this study, we showed that TLR7 activation significantly promoted interphotoreceptor retinoid-binding protein (IRBP)-specific Th17 responses by upregulating RORγt, IL-17, GM-CSF, and IL-23R expression in experimental autoimmune uveitis mice. In vivo administration of CL097 activated dendritic cells (DCs) and endowed them with an increased ability to activate IRBP-specific Th17 cells. CL097-t...
