Tertiary lymphoid organs (TLOs) are frequently observed in tissues affected by non-resolving inflammation as a result of infection, autoimmunity, cancer, and allograft rejection. These highly ordered structures resemble the cellular composition of lymphoid follicles typically associated with the spleen and lymph node compartments. Although TLOs within tissues show varying degrees of organization, they frequently display evidence of segregated T and B cell zones, follicular dendritic cell networks, a supporting stromal reticulum, and high endothelial venules...

Inflammatory cytokines are commonly elevated in acute depression and are associated with resistance to monoaminergic treatment. To examine the potential role of cytokines in the pathogenesis and treatment of depression, we carried out a systematic review and meta-analysis of antidepressant activity of anti-cytokine treatment using clinical trials of chronic inflammatory conditions where depressive symptoms were measured as a secondary outcome. Systematic search of the PubMed, EMBASE, PsycINFO and Cochrane databases, search of reference lists and conference abstracts, followed by study selection process yielded 20 clinical trials...

Nucleic acids sensors of the innate immune system recognize various RNA and DNA structures during infection to induce transcription of interferon and pro-inflammatory cytokines and activation of inflammasomes. Cytosolic RNA is recognized by RIG-I and MDA5, while intracellular DNA is sensed among others by cGAS, AIM2, IFI16 and RNA polymerase III. The diversity of nucleic acid species produced during infection in the cytosol and nucleus and the limited chemical differences between self and non-self nucleic acids challenge the host's innate pattern recognition system to ensure reliable sensing while avoiding immune activation by self nucleic acids...

OBJECTIVE: Epithelial ovarian cancer continues to be the deadliest gynecologic malignancy. Patients with both diabetes mellitus and obesity have poorer outcomes, yet research correlating metabolic abnormalities, such as metabolic syndrome, to ovarian cancer risk and outcomes is lacking. This article reviews the literature regarding metabolic derangements and their relationship to epithelial ovarian cancer, with a focus on potential mechanisms behind these associations. METHODS: PubMed and Google Scholar were searched for articles in the English language regarding epithelial ovarian cancer, obesity, diabetes mellitus, and metabolic syndrome, with a focus on studies conducted since 1990...

Renal cell carcinoma (RCC) comprises 2‑3% of all malignant tumors in adults. Many studies have established the key roles of smoking, hypertension and other components of metabolic syndrome in the occurrence of RCC. Diabetes mellitus (DM), one of the main consequences of metabolic syndrome, appears much more often in patients with RCC. The prognosis for patients suffering from both diabetes and RCC is worse than for those with kidney cancer only. Diabetes is linked to higher rate of recurrence and a greater number of distant metastases...

Adipokines are cytokines produced mainly by adipose tissue, besides many other tissues such as placenta, ovaries, peripheral-blood mononuclear cells, liver, muscle, kidney, heart, and bone marrow. Adipokines play a significant role in the metabolic syndrome and in cardiovascular diseases, have implications in regulating insulin sensitivity and inflammation, and have significant effects on growth and reproductive function. The objective of this review was to analyze the functions known today of adiponectin, leptin, resistin, and visfatin from placenta throughout childhood and adolescence...

IgG4-related disease (IgG4-RD) is a systemic disease characterized by elevated serum IgG4 levels and a strong infiltration of IgG4-positive plasma cells in various organs. IgG4-RD patients also frequently suffer from allergic diseases, including asthma and atopic dermatitis. It is well known that T helper type 2 (Th2) cells have an important role in the initiation of allergic diseases, and Th2 cytokines such as interleukin (IL)-4 and IL-13 promote class switching to IgG4. Therefore, IgG4-RD is considered to be a Th2-predominant disease...

Mesenchymal stem cells (MSCs) are non-hematopoietic cells that occur in almost all human tissues and can be cultured and expanded to large numbers in vitro. They secrete growth factors, cytokines, and chemokines and express Toll-like receptors on their surface, although multiple cell biological mechanisms remain unclear. MSCs are multi-potent and can differentiate into many cell types including adipocytes, neuronal cells and osteoclasts. Despite gaps in cell biology, because of their immunomodulatory and regenerative capacity, several hundred clinical trials have used MSCs for therapy of cancer, autoimmune diseases and control of inflammation during organ transplantation...

Commonly known for its critical role in calcium homeostasis and bone mineralization, more recently vitamin D has been implicated in haematological cancer pathogenesis and shows promise as an anti-cancer therapy. Serum levels of 25(OH)D3 , the precursor to the active form of vitamin D, calcitriol, are typically lower in patients with haematological disease compared to healthy individuals. This often correlates with worse disease outcome. Furthermore, diseased cells typically highly express the vitamin D receptor (VDR), which is required for many of the anti-cancer effects observed in multiple in vivo and in vitro cancer models...

BACKGROUND: Insulin, insulin-like growth factor-axis, adiponectin, and inflammatory markers are associated with breast cancer. Given that physical activity improve prognosis of breast cancer survivors, we investigated the effects of exercise on these markers as potential mediators between physical activity and breast cancer. METHODS: PubMed, EMBASE, CENTRAL, CINAHL, and SportDiscus were searched up to December 3, 2015 to identify RCTs that investigated the effect of exercise on insulin, insulin-like growth factor axis, and cytokines in breast cancer survivors...

BACKGROUND: Cancers escape immune surveillance via distinct mechanisms that involve central (negative selection within the thymus) or peripheral (lack of costimulation, receipt of death/anergic signals by tumor, immunoregulatory cell populations) immune tolerance. During the 1990s, moderate clinical benefit was seen using several cytokine therapies for a limited number of cancers. Over the past 20 years, extensive research has been performed to understand the role of various components of peripheral immune tolerance, with the co-inhibitory immune checkpoint molecules cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed death 1 (PD-1), and its ligand (PD-L1) being the most well characterized at preclinical and clinical levels...

Pannexins form channels at the plasma membrane surface that establish a pathway for communication between the cytosol of individual cells and their extracellular environment. By doing so, pannexin signaling dictates several physiological functions, but equally underlies a number of pathological processes. Indeed, pannexin channels drive inflammation by assisting in the activation of inflammasomes, the release of pro-inflammatory cytokines, and the activation and migration of leukocytes. Furthermore, these cellular pores facilitate cell death, including apoptosis, pyroptosis and autophagy...

Celiac disease (CD) is the most common autoimmune enteropathy, triggered by a deregulated immune response to gliadin. It has been hypothesized that human intestinal microbiota may interfere with the pathogenesis of the disease and in the clinical course of CD. In the present review, we analyzed the microbiota alterations observed in the course of CD, how they may influence the pathogenesis of CD, and the possible applications for a microbiota modulation in CD. In detail, most of the current literature underlined that the dysbiosis in CD is hallmarked by an increase in gram-negative and Bacteroidetes species, and by a decrease in Bifidobacteria and Lactobacilli...

Recent findings have publicized phosphoinositide-3-kinases (PI3Ks) as novel therapeutic targets, which are also purported to be involved in the complex pathophysiology of inflammatory and various other diseases. They are recognized to participate in the inflammatory cellular responses by modulating the growth, development and proliferation of various immune cells and hence, affect the release of various cytokines and other inflammatory mediators involved in these manifestations. The review presents a brief synopsis of the PI3K/AKT/mTOR signalling pathway along with the current and future prospects of targeting PI3Ks for various diseases, like malignant, autoimmune, inflammatory, cardiovascular, neurological disorders etc...

Sleep is a vital phenomenon related to immunomodulation at the central and peripheral level. Sleep deficient in duration and/or quality is a common problem in the modern society and is considered a risk factor to develop neurodegenerative diseases. Sleep loss in rodents induces blood-brain barrier disruption and the underlying mechanism is still unknown. Several reports indicate that sleep loss induces a systemic low-grade inflammation characterized by the release of several molecules, such as cytokines, chemokines, and acute-phase proteins; all of them may promote changes in cellular components of the blood-brain barrier, particularly on brain endothelial cells...

Given the relationship between anticholinergic activity (AA) and Alzheimer's disease (AD), we rereview our hypothesis of the endogenous appearance of AA in AD. Briefly, because acetylcholine (ACh) regulates not only cognitive function but also the inflammatory system, when ACh downregulation reaches a critical level, inflammation increases, triggering the appearance of cytokines with AA. Moreover, based on a case report of a patient with mild AD and slightly deteriorated ACh, we also speculate that AA can appear endogenously in Lewy body disease due to the dual action of the downregulation of ACh and hyperactivity of the hypothalamic-pituitary-adrenal axis...

CLS involves sudden loss of intravascular fluids into the interstitial spaces. CLS was described as a possible complication after SCT. Few studies report the incidence of CLS in pediatric populations. We aimed to assess CLS incidence, its risk factors, and impact on the survival. The clinical charts of patients <18 years of age transplanted at our institution between 2002 and 2012 were reviewed. CLS was defined by weight gain >3% in 24 hours and positive intake balance despite furosemide administration...
