The recent outbreak of SARS-CoV2 has emerged as one of the biggest pandemics of our century, with outrageous health, social and economic consequences globally. Macrophages may lay in the center of COVID-19 pathogenesis and lethality and treatment of the macrophage-induced cytokine storm has emerged as essential. Specialized pro-resolving mediators (SPMs) hold strong therapeutic potentials in the management of COVID-19 as they can regulate macrophage infiltration and cytokine production but also promote a pro-resolving macrophage phenotype. In this review, we discuss the homeostatic functions of SPMs acting directly on macrophages on various levels, towards the resolution of inflammation. Moreover, we address the molecular events that link the lipid mediators with COVID-19 severity and discuss the clinical potentials of SPMs in COVID-19 immunotherapeutics.

Background: Specialized pro-resolving mediators (SPMs) promote inflammatory resolution and homeostasis and are thought to have specific reprogramming effects on hman microglia. Decreased SPM levels have been correlated with chronic neuroinflammation, late-stage Alzheimer's disease (AD) and neuropathology in humans, yet few studies have explored the cellular signatures of resolution. Amyloid is though to bind one target resolution receptor, ChemR23, leading to internalization.

Purpose Of Review: This review summarizes recent literature falling broadly under the topic of n-3 polyunsaturated fatty acids (PUFAs) in the oncology setting, highlighting emerging themes and emphasizing novel explorations.
Recent Findings: Meta-analyses continue to confirm safety and efficacy of n-3 PUFA supplementation on reducing inflammation and improving survival in people with cancer. Common themes in recent studies emphasize improving tumor-directed efficacy and reducing toxicities of common cancer therapies.

During the process of acute lung injury (ALI) associated with sepsis, the α7nAChR in the cholinergic anti-inflammatory pathway (CAP) plays a crucial role. However, the roles of electroacupuncture (EA) and specialized pro-resolving mediators (SPMs) in this context remain unclear. In this study, we demonstrated that EA activates CAP via α7nAChR, reducing lung permeability and inflammatory cytokine release.

Unresolved chronic inflammation, a hallmark of cancer, promotes tumor growth and metastasis in various cancer types. In contrast to blocking inflammation, stimulation of resolution of inflammation is an entirely novel approach to "resolve" inflammation. Resolution of inflammation mechanisms in cancer includes clearance of tumor debris, counter-regulation of pro-inflammatory eicosanoids and cytokines, and suppression of leukocyte infiltration.

Asthma, is a common, significant and diverse condition marked by persistent airway inflammation, with a major impact on human health worldwide. The predisposing factors for asthma are complex and widespread. The beneficial effects of omega-3 (n-3) polyunsaturated fatty acids (PUFAs) in asthma have increasingly attracted attention recently.
