Abstract

Depression is highly prevalent in patients suffering from chronic inflammatory diseases. Dysregulated neuroinflammation and concomitant activated microglia play a pivotal role in the pathogenesis of depression. Paricalcitol (Pari), a vitamin D2 analogue, has been demonstrated to exert anti-inflammative effects on renal and cardiovascular diseases. In this study, mice were pretreated with Pari before being induced to acute depression-like behaviors by systemic lipopolysaccharide (LPS) injection. To determine the therapeutic effects of Pari, alterations in acute body weight, sucrose preference, forced swimming and tail suspension tests were assessed. Then, alterations of pro-inflammation cytokine IL1-β level and microglia activity in the hypothalamus, which are involved in the pathophysiology of depression, were examined. The results showed that Pari significantly alleviated systemic LPS injection induced depressive-like behaviors as shown by increased sucrose preference and decreased TST and FST immobility. Pari could specifically regulate microglia-mediated neuroinflammation process and local activity of renin-angiotensin system to exert its anti-depressant effects. This study demonstrated a potential for paricalcitol in treating depressive symptoms induced by systemic inflammation, particularly in patients with chronic hypertension.

  • The severity of depression is associated with the secretion level of circulating cytokines and chemokines, which compromise the BBB and then activate central immune responses.

    “Our previous findings and those of others indicate that the severity of depression is associated with the secretion level of circulating cytokines and chemokines, which compromise the blood–brain barrier (BBB) and then activate central immune responses [10–13].”

    From Chronic stress-induced depression requires the recruitment of peripheral Th17 cells into the brain (2022) · cites this paper as [12]

    The Introduction (page not provided) associates depression severity with circulating proinflammatory cytokines and says that compromised BBB and choroid plexus barriers lead to central immune activation. It does not extend the severity association to chemokines or say that circulating cytokines and chemokines themselves compromise the BBB. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
