Here's a few for depression and air pollution[1][2]
Here's some studies on anti-inflammatory treatments for treatment resistant depression[3]
And more relevant to the original topic, 5HT-2A receptor agonists may have anti-inflammatory effects. There's huge potential in a broad class of molecules that have been banned for moral, not medicinal, reasons.[4] Edit: picked another one [5]
Sorry, but none of these are studies about the relationship between depression and inflammation treatment.
Such a study would have to provide a measurement of the severity of the depression. Then split the patients in two groups. Give one group a placebo and the other one the inflammation treatment. And then compare the depression severity in those groups after the treatment.
