Platelet-derived growth factor-BB (PDGF-BB) is recognized as a potential player in a paracrine manner in tumor stroma development. PDGF-BB has an autocrine growth function in lung cancer cells; however, the mechanism in nonsmall-cell lung cancer is not fully understood. In this study, we report that PDGF-BB increased monocyte chemoattractant protein-1 (MCP-1)-dependent macrophage recruitment and that expression of metastatic genes increased in A549 cells cocultured with RAW 264.7 macrophages. Similar to exogenous PDGF-BB, PDGF-BB might have a self-stimulation in invasion of cancer cells during reciprocal activation of cancer cells and tumor-associated macrophages through secretion of soluble proteins...

Type III interferon (IFN) is a newly established IFN that shows roles different from those of type I and II IFNs. However, the effect of type III IFN on the prognosis of patients with gastric cancer (GC) is controversial. This study aimed to investigate the effects of serum IFN-α, IFN-β, IFN-γ, IFN-λ1, and IFN-λ2/3 levels on the survival of patients with GC. LEGENDplex bead-based immunoassays were used to analyze the serum IFN-α, IFN-β, IFN-γ, IFN-λ1, and IFN-λ2/3 levels in patients with GC and healthy volunteers...

Abnormal alveolar formation and excessive disordered elastin accumulation are key pathological features in bronchopulmonary dysplasia. Transforming growth factor (TGF)-β is an important regulator of the extracellular matrix in the developing lung. To determine if increased TGF-β would injure alveolar development by activating TGF-β signaling and by influencing the expression of elastogenesis-related protein, we performed intraperitoneal injection of newborn mice with the TGF-β-neutralizing antibody 1D11 and observed whether 1D11 had a protective role in the oxygen (O2 )-exposed newborn mouse lung...

The authors aim to understand how lymphocyte populations could predict the course of multiple sclerosis (MS) in people treated with interferon-β (IFN-β). Twenty-five male patients and 72 female patients were analyzed in the study. Peripheral blood samples were taken before and 5 years after the treatment with IFN-β. Lymphocyte subsets were analyzed by flow cytometry. The authors compared lymphocyte parameters between confirmed sustained progression (CSP) and non-CSP groups by using Welch's one-way analysis of means or a chi-square test of independence...

Liver sinusoidal endothelial cells (LSECs) are highly specialized and involved in hepatic regeneration by interacting with hepatic stellate cells (HSCs) and hepatocytes in a paracrine manner. However, hepatic injury can impair cellular activity and lead to endothelial dysfunction, eventually inducing the development of critical hepatic disease, including cirrhosis. Because LSECs exert their effects through paracrine factors, maintenance of paracrine potentials and survival activity in LSECs under injury stress is a critical strategy for inhibiting disease progression...

Today, improvements in diagnostic and therapeutic options allow patients with autoimmune diseases (ADs) to live longer and have more active lives compared with patients receiving conventional anti-inflammatory therapy just two decades ago. Current therapies for ADs aim to inhibit immune cell activation and effector immune pathways, including those activated by cytokines and cytokine receptors. Understandably, such goals become more complicated in patients with long-term established ADs who develop parallel chronic or comorbid conditions, including life-threatening diseases, such as cancer...

CD4+ T helper (Th) cells are important regulators of cellular immune response. Newly discovered interleukin (IL)-17-producing CD4+ T cells are known as T helper 17 cells (Th17). They are distinct subset from the T helper type 1 (Th1) and 2 (Th2) lineages. The differentiation of Th17 cells has been intensively studied; however, the role of Th17 cells in different diseases including cancer is still under investigation. Besides IL-17 family cytokines, Th17 cells produce IL-22, IL-21, and IL-26. The dysregulated function of Th17 cells and their cytokines could contribute to pathology of diseases, including cancer...

Mesangial cell (MC) activation and macrophage infiltration are 2 major events closely related with each other in mesangial proliferative glomerulonephritis. In the anti-Thy 1 nephritis model, macrophages mediate the damage and also the expansion of mesangium through secreting various inflammatory factors; however, in glomerular microenvironment how MCs affect macrophage activity in the presence of various stimuli have not yet been understood. In the present study, we found that resting human MCs (HMCs) constitutively expressed chemokine [C-C motif] ligand 2 (CCL-2) and interleukin (IL)-6 and induced M2 polarization of macrophages in the coculture system...

Impaired interleukin-2 (IL-2) production was reported in systemic lupus erythematosus (SLE). The aim of this study was to investigate the clinical relevance of serum IL-2 and therapeutic effects of recombinant IL-2 (rIL-2) in SLE, especially in lupus nephritis (LN). Decreased serum IL-2 was found in patients with active LN (P = 0.014) and correlated with 24-h urine protein excretion (r = -0.281, P = 0.026). Compared with LN patients with decreased levels of serum IL-2, patients with increased levels had better remission rate (P = 0...

Cytokines are major regulators of innate and adaptive immunity that enable cells of the immune system to communicate over short distances. Cytokine therapy to activate the immune system of cancer patients has been an important treatment modality and continues to be a key contributor to current clinical cancer research. Interferon alpha (IFNα) is approved for adjuvant treatment of completely resected high-risk melanoma patients and several refractory malignancies. High-dose interleukin-2 (HDIL-2) is approved for treatment of metastatic renal cell cancer and melanoma, but both agents are currently less commonly used with the development of newer agents...

The innate immune response is defined as an immensely complex and sophisticated process aimed at defending the organism against any disturbance in the body homeostasis, including invading pathogens. It requires a close cooperation of a vast amount of different cell types, recognized as inflammatory migrating cells, as well as stationary cells that form tissues. Moreover, innate immune mechanisms require an efficient functioning of various humoral components that exert a significant impact on physiological and pathological processes...

Antitumor activity of classically activated macrophage (Mϕ) may be impaired within the tumors, spleen, and bone marrow. Thus, it is possible to boost its antitumor activity after its pulsing with necrotic tumor cell lysates combined with an adjuvant. We set out to determine the potential adjuvant effects of thymoquinone (TQ; 2-isopropyl-5-methyl-1,4-benzoquinone, C10 H12 O2 ) on both functional activities of classically activated Mϕs, pulsed or not with necrotic Jurkat T cell line lysates (NecrJCL), and the balance of antitumor cytokines (ATCs) versus immunosuppressive cytokines (ISCs) during crosstalk with autologous human CD4+ T cells...

Interferon-gamma (IFNG) has long been implicated as a central orchestrator of antitumor immune responses in the elimination stage of the immunoediting paradigm. However, mounting evidence suggests that IFNG may also have important and significant protumor roles to play in the equilibrium and escape phases through its regulatory effects on immunoevasive functions that promote tumorigenesis. These seemingly contradictory effects of IFNG undoubtedly play profound roles in not only the activation of inflammatory response to cancer but also in the determination of its outcome...

Interleukin-33 (IL-33) is a cytokine with pleiotropic functions in various diseases; however, its role in the antitumor immune response is still unclear. We found the expression of IL-33/ST2 in nonsmall cell lung tumor microenvironment. Furthermore, we found that IL-33 promoted effector functions of CD8+ T cells that play a critical role in antitumor immune response. In addition, we found that IL-33 enhanced tumor vaccine effector functions in mice. Altogether, these findings suggest that IL-33, through facilitates CD8+ T cells in microenvironment to provide a profound effect in antitumor immunotherapy...
