“…Since MIF has been directly implicated in the regulation of endothelial differentiation [84], we believe that MIF as a tumor promoter proves again that monocytes-derived ECs can be a subpopulation of M2-TAMs, reaching the tumor to favor angiogenesis by also making part of the blood vessel structures. Interestingly, an oxidized isoform of MIF was identified as a prognostic biomarker and therapeutic target in inflammatory disease and cancer [85,86], showing again that the pro-oxidative tumor microenvironment is playing a role in angiogenesis.…”

Bone marrow contains endothelial progenitor cells (EPCs) that, upon pro-angiogenic stimuli, migrate and differentiate into endothelial cells (ECs) and contribute to re-endothelialization and neo-vascularization. There are currently no reliable markers to characterize EPCs, leading to their inaccurate identification. In the past, we showed that, in a panel of tumors, some cells on the vessel wall co-expressed CD14 (monocytic marker) and CD31 (EC marker), indicating a putative differentiation route of monocytes into ECs. Herein, we disclosed monocytes as potential EPCs, using in vitro and in vivo models, and also addressed the cancer context. Monocytes acquired the capacity to express ECs markers and were able to be incorporated into blood vessels, contributing to cancer progression, by being incorporated in tumor neo-vasculature. Reactive oxygen species (ROS) push monocytes to EC differentiation, and this phenotype is reverted by cysteine (a scavenger and precursor of glutathione), which indicates that angiogenesis is controlled by the interplay between the oxidative stress and the scavenging capacity of the tumor microenvironment.Over the last decade, different studies reported EPCs as essential in restoring injured vessels. EPCs belong to a subset of cells, arising from hematopoietic stem cells in bone marrow; upon pro-angiogenic stimuli, they proliferate, migrate, and differentiate into endothelial cells (ECs) [4][5][6]. Some reports addressing EPCs and disease, such as systemic sclerosis, showed contradictory and discrepant results about EPCs mobilization and differentiation; in part, because there is a lack of a precise panel of cell surface markers used for the characterization of this subset of cells [4][5][6][7][8][9][10]. In mouse embryonic vascular endothelium, erythro-myeloid progenitors (EMPs) can differentiate into ECs [11] and in a mouse model of carotid injury, monocytes (CD14 + cells) are capable of improving re-endothelialization [12]. In vivo and in vitro targeting of Tie2-monocytes decreases angiogenesis by abrogating EC proliferation [13][14][15] and an in vivo CCR2 (chemokine (C-C motif) receptor 2) knockout impairs monocytes recruitment and VEGFA (also named VEGF, vascular endothelial growth factor) expression, accompanied by a reduction in the angiogenesis rate [16]. The release of cytokines and pro-angiogenic factors (e.g., VEGFA, VEGFC, and VEGFD, TNFα (tumor necrosis factor α), IL-8 (interleukin-8), and FGF-2 (fibroblast growth factor-2), and extracellular matrix (ECM) modifying proteins (e.g., metalloproteinase-9 (MMP-9)) by macrophages enhances the tissue's ability to support capillary sprouting and vascular density [17,18]. The precise mechanism by which monocytes influence angiogenesis in tissue development, homeostasis, and diseases is not fully understood. However, different studies, have shown that under in vitro pro-angiogenic pressure, blood mononuclear cells can acquire endothelial markers and morphology [19][20][21]. In addition, in a previous study, we showed that some ECs sim...

“…Recent studies have shown that circulating MIF can occur in two forms: oxidized MIF (oxMIF) and reduced MIF (redMIF) [64,65]. Accordingly, RedMIF is the isoform that can be more abundantly expressed, and is also detectable in healthy subjects, whereas oxMIF represents the disease-related isoform which is predominant in the blood and on the surface of cells isolated from patients suffering from chronic inflammatory disorders and cancer [64,65].…”

The Role of Macrophage Migration Inhibitory Factor in Alzheimer′s Disease: Conventionally Pathogenetic or Unconventionally Protective?

Recent preclinical and clinical observations have offered relevant insights on the etiopathogenesis of late onset Alzheimer′s disease (AD) and upregulated immunoinflammatory events have been described as underlying mechanisms involved in the development of AD. Macrophage migration inhibitory factor (MIF) is a pleiotropic cytokine produced by several cells of the innate and adaptive immune system, as well as non-immune cells. In the present review, we highlight experimental, genetic, and clinical studies on MIF in rodent models of AD and AD patients, and we discuss emerging therapeutic opportunities for tailored modulation of the activity of MIF, that may potentially be applied to AD patients. Dismantling the exact role of MIF and its receptors in AD may offer novel diagnostic and therapeutic opportunities in AD.

“…Thiele et al (2015) previously described that MIF occurs in two immunologically distinct conformational isoforms, and identified oxMIF as the disease-related isoform predominantly expressed in patients with inflammatory diseases (Thiele et al, 2015) and in cancer patients (Schinagl et al, 2016). As BaxB01 specifically binds oxMIF (Thiele et al, 2015), we investigated the antibody's PK and minimally effective dose levels, and defined the exposures associated with optimal pharmacological activity.…”

New therapeutic agents are needed to overcome the toxicity and suboptimal efficacy observed in current treatment of glomerulonephritis (GN). BaxB01 is a fully human monoclonal antibody targeting a disease-related immunologically distinct isoform of Macrophage migration Inhibitory Factor (MIF), designated oxidized MIF (oxMIF) and locally expressed in inflammatory conditions. We report the pharmacokinetic profile of BaxB01, and its dose and exposure-related disease-modifying activity in experimentally induced rat GN. BaxB01 bound to rat oxMIF with high affinity and reduced rat macrophage migration in vitro. After intravenous administration in rats, BaxB01 demonstrated favorable pharmacokinetics, with a half-life of up to nine days. Disease modification was dose-related (≥ 10mg/kg) as demonstrated by significantly reduced proteinuria and diminished histopathological glomerular crescent formation. Importantly, a single dose was sufficient to establish an exposure-related, anti-inflammatory milieu via amelioration of glomerular cellular inflammation. Pharmacodynamic modeling corroborated these findings, consistently predicting plasma exposures that were effective in attenuating both anti-inflammatory activity and reducing loss of kidney function. This pharmacologic benefit on glomerular function and structure was sustained during established disease, while correlation analyses confirmed a link between the antibody's anti-inflammatory activity and reduced crescent formation in individual rats. Finally, safety assessment in rats showed that the experimental therapeutic was well tolerated without signs of systemic toxicity or negative impact on kidney function. These data define therapeutically relevant exposures correlated with mechanism-based activity in GN, while toxicological evaluation suggests a large therapeutic index and provides evidence for achieving safe and effective exposure to a MIF isoform-directed therapeutic in nephritis-associated disease.
