Immune suppression and immune activation in depression

Effects of carotenoids, immune activation and immune suppression on the intensity of chronic coccidiosis in greenfinches.

Allocation trade-offs of carotenoids between their use in the immune system and production of integumentary colouration have been suggested as a proximate mechanism maintaining honesty of signal traits. We tested how dietary carotenoid supplementation, immune activation and immune suppression affect intensity of coccidian infection in captive greenfinches Carduelis chloris, a passerine with car...

THE EFFECTS OF DEPRESSION ON ENDOICRINE AND IMMUNE SYSTEMS

To study the effect of depression on the endocrine and immune systems, 557 male freshman and sophomore medical students (20-30 years old) were given Beck's Depression Inventory. Students with marks 5 or above were selected as the control (n=26) and those with marks of 20 or higher were chosen as the test group (n=27). All of the students were subjected to the following tests: CBC, different...
