MicroRNA 21 is a homeostatic regulator of macrophage polarization and prevents prostaglandin E2-mediated M2 generation.

open access: yesPLoS ONE, 2015
Macrophages dictate both initiation and resolution of inflammation. During acute inflammation classically activated macrophages (M1) predominate, and during the resolution phase alternative macrophages (M2) are dominant. The molecular mechanisms involved

POSS‐PEG‐NHS and GSH Cocrosslink DPAV to Prepare Anticalcification Bioprosthetic Scaffold With Enhanced Reendothelization, Anti‐inflammation, and Anti‐ROS

open access: yesAdvanced Healthcare Materials, EarlyView.
POSS‐PEG‐NHS and GSH cocrosslinked DPAV to prepare a multifunctional anticalcification valve substitute. This modification enhances mechanical properties, hemocompatibility, and re‐endothelialization while promoting anti‐inflammatory M2 macrophage infiltration and reducing calcification.

In vivo imaging and quantitative analysis of leukocyte directional migration and polarization in inflamed tissue [PDF]

open access: yes, 2009
Directional migration of transmigrated leukocytes to the site of injury is a central event in the inflammatory response. Here, we present an in vivo chemotaxis assay enabling the visualization and quantitative analysis of subtype-specific directional ...

Treatment of silicosis with quercetin depolarizing macrophages via inhibition of mitochondrial damage-associated pyroptosis

open access: yesEcotoxicology and Environmental Safety
Macrophage polarization facilitates the inflammatory response and intensified fibrosis in the silicosis microenvironment by a mechanism related to macrophage pyroptosis, although the upstream target remains poorly defined.

Macrophage Polarization In The Tumor Microenvironment

open access: yesRedox Biology, 2015
Tumor associated macrophages (TAMs) are known to support tumor progression and their accumulation is generally associated with poor prognosis. The shift from a tumor-attacking to a tumor-supportive macrophage phenotype is based on an educational program that, at least in part, is initiated by apoptotic tumor cells.We explored the macrophage phenotype ...

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

A cardinal role for cathepsin D in co-ordinating the host-mediated apoptosis of macrophages and killing of pneumococci [PDF]

open access: yes, 2011
The bactericidal function of macrophages against pneumococci is enhanced by their apoptotic demise, which is controlled by the anti-apoptotic protein Mcl-1.

Temporal Immune and Metabolic Shifts Drive the Anti‐Tumor Efficacy of Resiquimod‐Loaded Nanoparticles in Peritoneal Carcinomatosis

open access: yesAdvanced Healthcare Materials, EarlyView.
Peritoneal carcinomatosis is a hard‐to‐treat spread of abdominal cancers that often returns after therapy. Nanoparticles were developed to retain an immune‐boosting drug in the abdomen. When combined with chemotherapy in mice, this approach eliminated tumors in many cases and prevented recurrence, helping the immune system mount a stronger, longer ...

Blimp-1 orchestrates macrophage polarization and metabolic homeostasis via purine biosynthesis in sepsis

open access: yesCell Death and Disease
Sepsis is a life-threatening condition characterized by a dysregulated immune response to infection, leading to systemic inflammation and organ dysfunction.
