I have a hammer, so I see nails everywhere...
Serotonin and melatonin are mutual inhibitors and often have opposing effects (as well as the former being the precursor of the latter).
Is is well known that melatonin boosts immune responses and in situations where melatonin is depressed (e.g., in constant light), both cellular and humoral immunity drop.
A friend of mine, Chris Moore, published a couple of papers on this in quail, if you are interested in tracking that stuff down.
