Prevalence of treatment-resistant depression in primary care: cross-sectional data. Br J Gen Pract2013;63:e852-8. Clinical and experimental evidence suggests that, in addition to treating depression, mirtazapine also alters liver innate immunity and suppresses immune-driven hepatic macrophage activation.

Liver macrophages, Kupffer cells, represent the largest collection of fixed macrophages in the body and are critical in regulating hepatic immunity. In addition to their capacity to regulate inflammation, Kupffer cells are key sentinels for clearing blood-borne pathogens, preventing their dissemination within the body. This process involves pathogen capture, phagocytosis, and activation-induced killing via reactive oxygen species (ROS) production.

Therefore, we speculated that mirtazapine might adversely alter Kupffer cell pathogen-associated activation and killing. Methods: Armpits were treated with mirtazapine and time-dependent changes in Kupffer cells were characterized using intravital microscopy. Macrophage and neutrophil responses, bacterial dissemination, and liver damage were assessed following i.

Results: Mirtazapine rapidly (within 1. Neutrophil dynamics were altered with reduced cellular recruitment to the liver following infection. Bacterial dissemination post-intravenous administration was not altered by mirtazapine treatment; however, hepatic abscess formation was significantly reduced. Moreover, these changes in Kupffer cells were linked to a beneficial reduction in hepatic abscess size.

In contrast to our initial speculation, mirtazapine may have beneficial effects in sepsis and warrants further exploration. Treatment of animals with the atypical antidepressant mirtazapine activates liver macrophages. This activation enhances the ability of these cells to kill bacteria while simultaneously reducing the overall inflammatory response. This liver reprogramming results in an efficient immune response and pathogen clearance while limiting inflammation-mediate collateral damage to the liver.

However, despite these clinical observations there is limited understanding of the impact of antidepressants on immunity. Recently, using a large epidemiological database, we identified a beneficial effect of the atypical antidepressant mirtazapine on adverse clinical liver outcomes in patients with the autoimmune liver disease primary biliary cholangitis Timentin Injection (Ticarcillin Disodium and Clavulanate Potassium Galaxy)- FDA. Mirtazapine, classified as an atypical antidepressant, is commonly prescribed for the treatment of major depression.

Interestingly, these receptors are particularly enriched in the liver, especially on macrophages (12). In translational bench research, we used a mouse model of immune-mediated liver injury to define mechanism(s), replicating many clinical Timentin Injection (Ticarcillin Disodium and Clavulanate Potassium Galaxy)- FDA from patients with autoimmune liver disease, and found that mirtazapine had a marked impact on hepatic innate-immune activation.

Although the inflammation-suppressive effect of mirtazapine in experimental immune-driven liver injury was beneficial in attenuating liver damage, hepatic macrophages also have well-defined and critical roles in the capture and killing of pathogenic bacteria within the circulation, including S.

This biological action of macrophages located within hepatic sinusoids is key for preventing bacterial seeding of the liver and associated liver damage, and in stopping Timentin Injection (Ticarcillin Disodium and Clavulanate Potassium Galaxy)- FDA dissemination of bacteria entering the circulation (14, 15). To examine this possibility, we used the well-characterized mouse model of S.

Animals were housed in a pathogen-free environment at the University of Calgary. All experimental protocols were approved by the University of Calgary Animal Care Committee and were in compliance with guidelines from the Canadian Council for Animal Care (AC18-0050). Antibodies and fluorescent probes are listed in Supplementary Table 1. Liver perfusion was assessed following i. Surgical preparation of animals for intravital microscopy of the mouse liver was performed as previously described (18).

For surgery, a laparotomy was performed, and the abdominal skin and peritoneum were removed to expose the liver. The falciform ligament was cut after securing the sternum away from the liver using a suture. The mouse was moved to a heated stage, to maintain body temperature throughout image acquisition, and placed on its right side.

Using a wet cotton swab, the stomach was manipulated to maneuver the liver into place on a glass coverslip. The gastrointestinal tract was moved away from the liver and secured by wrapping in wet Timentin Injection (Ticarcillin Disodium and Clavulanate Potassium Galaxy)- FDA. One layer of wet tissue was placed on the liver to preserve physiological conditions, prevent drying, and diminish movement.

Body temperature was maintained via heated stage throughout image acquisition. Still images from single channel fluorescence (platelets, neutrophil elastase, FITC contrast agent, neutrophils, Kupffer cells) were exported from acquisition software (Leica LasX) as.

Minimum threshold values were applied to decrease background fluorescence signal. The same threshold values were applied to images from all treatment groups within a single experiment. Liver samples were collected and put into formalin for fixation. After embedding in paraffin, 4. Images were taken with a Leica Aperio AT2 scanscope microscope, and then analyzed using Image J software urethra catheter, U.

For Staphylococcus aureus infections, bacteria (USA300) was grown to midlog phase in brain-heart infusion broth, washed, resuspended in saline, and injected i. Organs were harvested, weighed, and homogenized. Given the marked shift in cell morphology Timentin Injection (Ticarcillin Disodium and Clavulanate Potassium Galaxy)- FDA 1. Although still significantly more round in mirtazapine vs vehicle treated animals, KCs had started to shift back to a less rounded phenotype by 24 h post-mirtazapine (Figure 1C, Supplemental Movie 1).

The early marked shift video sex very young cellular morphology clearly demonstrates rapid activation of liver macrophages following mirtazapine treatment.

We next assessed whether mirtazapine-induced cellular activation and associated shape changes would affect the capacity of KCs to capture particles from the circulating blood (22). Results show that sinusoidal KCs have a similar Timentin Injection (Ticarcillin Disodium and Clavulanate Potassium Galaxy)- FDA to capture beads from the hepatic circulation in both mirtazapine and vehicle treated groups (Figures 1D, E).

As beads are inert particles, we confirmed our results using live S.
