Does a2A adenosine receptor agonist and PDE4 inhibition delays inflammation but fail to reduce injury in experimental obstructive nephropathy?
A2A receptor activation and PDE4 inhibition transiently reduce renal macrophage infiltration, but do not ameliorate the renal response to UUO. We speculate that the persistent stimulus for inflammation triggered by UUO cannot be reversed by agents that suppress inflammatory cell activation alone.
These results support the assumption that states of depression cause general descriptions of depression-relevant behaviour. The specific characteristics that have been perceived confirm the general concepts, which however make the patient prone to the respective selective perceptions. Persons suffering from a reactive form of depressive mood cannot be assumed to have this tendency of self-affirmation. Their depressive state may be maintained by perseverating general pessimistic schemes.
