Minocycline alters behavior, microglia and the gut microbiome in a trait-anxiety-dependent manner

Abstract: Major depressive disorder is the main cause of disability worldwide with imperfect treatment options. However, novel therapeutic approaches are currently discussed, from augmentation strategies to novel treatments targeting the immune system or the microbiome-gut-brain axis. Therefore, we examined the potential beneficial effects of minocycline, a tetracycline antibiotic with pleiotropic, immunomodulatory action, alone or as augmentation of escitalopram on behavior, prefrontal microglial density, and the gut m… Show more

“…in the mouse, potentially reflecting its action on the gut when given orally. 114 However, in a mouse model, specific inactivation of microglia with PLX5622 reduces food intake in high-fat diet-fed mice (but, as discussed, not in chow-fed 107 ). In addition, we recently demonstrated that microglial depopulation in the Cx3cr1-Dtr transgenic rat leads to an acute suppression of food intake and a corresponding weight loss that is restored as the microglia repopulate.…”

“…In humans, suppression of microglial activity with minocycline can lead to weight loss, a finding that is opposite to the effects of this compound when given i.c.v. in the mouse, potentially reflecting its action on the gut when given orally . However, in a mouse model, specific inactivation of microglia with PLX5622 reduces food intake in high‐fat diet‐fed mice (but, as discussed, not in chow‐fed).…”

“…Verändern sich bei Tiermodellen für Depression die Darmmikrobiota, ihr kollektives Genom genannt Darmmikrobiom, und die an der Mikrobiota-Darm-Hirn-Achse beteiligten Systeme ebenfalls? Eine Studie unserer Arbeitsgruppe konnte zeigen, dass in einer Rattenzuchtlinie für hohes angst-und depressionsähnliches Verhalten (high anxiety-related behaviour, HAB-Ratten) die β-Diversität der Darmmikrobiota (die Diversität zwischen 2 Organismen) im Vergleich zu nicht selektierten Tieren markant verändert ist [47]. Ähnlich zu Tieren mit angeborenem Verhalten kann bei einem erworbenen Verhaltensphänotyp eine Veränderung in der Darmmikrobiotadiversität festgestellt werden.…”

“…Durch die antibakteriellen Effekte auf spezifische Bakterien (wie gram-positiv oder -negativ) reduzieren Antibiotika spezifisch die Menge und die Zusammensetzung der Darmmikrobiota innerhalb eines Organismus (auch genannt α-Diversität), was noch nach 2 Jahren nachgewiesen werden kann [47,53,54]. Dabei können längerfristigen Nebenwirkungen wie Diarrhoe, verstärkte Pathogenkolonisierung oder verlängerte Immunaktivität im Menschen [55] und in Mäusen [56,57] auftreten.…”
