Mylabris phalerata (MP) is an insect used in oriental herbal treatments for tumor, tinea infections, and stroke. Recent studies have shown that tumor-associated macrophages (TAM) have detrimental roles such as tumor progression, angiogenesis, and metastasis. Although TAM has phenotypes and characteristics in common with M2-polarized macrophages, M1 macrophages have tumor suppression and immune stimulation effects. Medicines polarizing macrophages to M1 have been suggested to have anticancer effects via the modulation of the tumor microenvironment...

Extracellular bacterial ribonucleases such as binase from Bacillus pumilus possess cytotoxic activity against tumor cells with a potential for clinical application. Moreover, they may induce activation of tumor-derived macrophages either into the M1-phenotype with well-documented functions in the regulation of the antitumor immune response or into M2-macrophages that may stimulate tumor growth, metastasis, and angiogenesis. In this study, binase or endogenous RNase1 (but not RNA or short oligonucleotides) stimulated the expression of activated NF-κB p65 subunit in macrophages...

Inflammatory and fibrotic events that drive chronic pancreatitis (CP) are likely orchestrated via signaling of soluble cytokines and chemokines systemically and within the pancreas. However, a comprehensive summary of the expression of such factors during CP has not been reported to date. This information is important given continued interest in targeting cytokines that influence CP pathogenesis. Reported data on the expression change of soluble immunomodulatory factors in human CP patients were identified via a literature search using a single search term...

The outcome of a host-pathogen interaction is determined by the conditions of the host, the pathogen, and the environment. Although numerous proteomic studies of in vitro-grown microbial pathogens have been performed, in vivo proteomic approaches are still rare. In addition, increasing evidence supports that in vitro studies inadequately reflect in vivo conditions. Choosing the proper host is essential to detect the expression of proteins from the pathogen in vivo. Numerous studies have demonstrated the suitability of zebrafish (Danio rerio) embryos as a model to in vivo studies of Pseudomonas aeruginosa infection...

Accumulating evidence suggests a role for gamma delta (γδ) T cells as unexpected drivers of tumor development and progression. These protumoral γδ T cells are abundant in the tumor microenvironment in both mouse and human. They promote tumor progression by: (i) inducing an immunosuppressive tumor microenvironment and angiogenesis via cytokine production; (ii) functioning as regulatory T (Treg)/T helper 2 (Th2)-like cells; (iii) interfering with dendritic cell (DC) effector function; and (iv) inhibiting antitumor adaptive T cell immunity via the programmed death-1 (PD-1)-programmed death ligand-1 (PD-L1) pathway...

Since lithium (Li⁺) plays roles in angiogenesis, the localized and controlled release of Li⁺ ions from bioactive glasses (BGs) represents a promising alternative therapy for the regeneration and repair of tissues with a high degree of vascularization. Here, microparticles from a base 45S5 BG composition containing (wt %) 45% SiO₂, 24.5% Na₂O, 24.5% CaO, and 6% P₂O₅, in which Na₂O was partially substituted by 5% Li₂O (45S5.5Li), were obtained. The results demonstrate that human umbilical vein endothelial cells (HUVECs) have greater migratory and proliferative response and ability to form tubules in vitro after stimulation with the ionic dissolution products (IDPs) of the 45S5...

BACKGROUND AND OBJECTIVE: The use of pulsed dye laser (PDL) and fractional CO2 (FX CO2 ) laser therapy to treat and/or prevent scarring following burn injury is becoming more widespread with a number of studies reporting reduction in scar erythema and pruritus following treatment with lasers. While the majority of studies report positive outcomes following PDL or FX CO2 therapy, a number of studies have reported no benefit or worsening of the scar following treatment. The objective of this study was to directly compare the efficacy of PDL, FX CO2 , and PDL + FX CO2 laser therapy in reducing scarring post burn injury and autografting in a standardized animal model...

Stress-induced allostatic load affects a variety of biological processes including synaptic plasticity, angiogenesis, oxidative stress, and inflammation in the brain, especially in the hippocampus. Erythropoietin (EPO) is a pleiotropic cytokine that has shown promising neuroprotective effects. Recombinant human EPO is currently highlighted as a new candidate treatment for cognitive impairment in neuropsychiatric disorders. Because EPO enhances synaptic plasticity, attenuates oxidative stress, and inhibits generation of proinflammatory cytokines, EPO may be able to modulate the effects of stress-induced allostatic load at the molecular level...

Numerous studies on the application of low temperature plasma (LTP) have produced impressive results, including antimicrobial, antitumor, and wound healing effects. Although LTP research has branched out to include medical applications, the detailed effects and working mechanisms of LTP on wound healing have not been fully investigated. Here, we investigated the potential effect of inducing growth factor after exposure to LTP and demonstrated the increased expression of angiogenic growth factor mediated by LTP-induced HIF1α expression in primary cultured human dermal fibroblasts...

Tumor associated macrophages (TAMs) promote angiogenesis, tumor invasion and metastasis, and suppression of anti-tumor immunity. These myeloid cells originate from monocytes, which differentiate into TAMs upon exposure to the local tumor microenvironment. We previously reported that Kaposi's sarcoma-associated herpes virus (KSHV) infection of endothelial cells induces the cytokine angiopoietin-2 (Ang-2) to promote migration of monocytes into tumors. Here we report that KSHV infection of endothelial cells induces additional cytokines including interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-13 (IL-13) that drive monocytes to differentiate and polarize into TAMs...

Vascular endothelial growth factor (VEGF) is known as a key mediator of angiogenesis, but there is also evidence of its broad significance in neurogenesis and neuroprotection. Cytokines of the VEGF family affect neovascularization and neural development in the brain, particularly during cerebral ischemia, in which there is a coordinated interaction of angiogenesis and neurogenesis that contributes to rapid functional recovery. This review examines the involvement of VEGF family members and their receptors in physiological and pathophysiological processes as well as the relationship between VEGF-A plasma levels and ischemic stroke...
