Hepatic stellate cells (HSCs), also known as perisinusoidal cells, are pericytes found in the perisinusoidal space of the liver. HSCs are the major cell type involved in liver fibrosis, which is the formation of scar tissue in response to liver damage. When the liver is damaged, stellate cells can shift into an activated state, characterized by proliferation, contractility and chemotaxis. The activated HSCs secrete collagen scar tissue, which can lead to cirrhosis. Recent studies have shown that in vivo activation of HSCs by fibrogenic agents can eventually lead to senescence of these cells, which would contribute to reversal of fibrosis although it may also favor the insurgence of liver cancer...

Hedgehog (Hh) signaling is essential for intestinal homeostasis and has been associated with inflammation and tissue repair. We hypothesized that Hh signaling could affect the inflammatory process in inflammatory bowel disease (IBD). For this purpose, colon specimens from the inflamed and non-inflamed mucosa of 15 patients with Crohn's disease (CD), 15 with ulcerative colitis, and 15 controls were analyzed by immunohistochemistry and real-time PCR. The production and modulation of cytokines were measured by ELISA from culture explants...

The aim of the study was to evaluate CXCL4 levels in undifferentiated connective tissue disease at risk for SSc (UCTD-SSc-risk) and confirm its increase and investigate its prognostic value. Serum CXCL4 levels were measured in 45 patients and 24 controls. CXCL4 was significantly higher in UCTD-SSc-risk patients than in controls. It resulted higher in patients with a shorter disease duration and in those lacking capillaroscopic alterations. We confirm that CXCL4 levels are increased in UCTD-risk-SSc patients...

Organic acidurias are inherited metabolic diseases due to the deficiency of an enzyme or a transport protein involved in one of the several cellular metabolic pathways devoted to the catabolism of amino acids, carbohydrates or lipids. These deficiencies result in abnormal accumulation of organic acids in the body and their abnormal excretion in urine. More than 65 organic acidurias have been described; the incidence varies, individually, from 1 out of 10,000 to >1 out of 1000,000 live births. Collectively, their incidence approximates 1 out of 3000 live births...

Immune reconstitution after high-dose chemotherapy and stem cell transplantation plays a key role in restoring immunocompetence including defense against infection, immune regulation, and onco-immune surveillance. In this work, we examined the recovery of mucosal-associated invariant T (MAIT) cells, recently discovered innate-like T cells, after various types of myeloablative chemotherapy and autologous peripheral blood stem cell transplantation in 29 patients. We show that MAIT cells are relatively resistant to myeloablative conditioning...

The Cyclin D1 protein has been extensively studied over the last decades, for its various roles in physiological processes, both in normal and cancer cells. Gene amplifications and overexpression of CCND1 are frequently reported in several types of cancers, including breast carcinomas, showing the increasing relevance of Cyclin D1 in tumorigenesis. Little is known about the role of this protein in the metastatic process, and the main objective of this study was to evaluate the importance of the CCND1 as a potential marker of tumor progression in breast carcinomas, in a sample collected in Southern Brazil...

Primary biliary cirrhosis (PBC) is a progressive autoimmune liver disease in which monocytes/macrophages infiltration and skewed T helper type (Th) 1 and Th17 cell responses participate in the development of the disease. Human peripheral blood monocytes are heterogeneous and can be divided into classical CD14(high)CD16(-), intermediate CD14(high)CD16(+), and nonclassical CD14(low)CD16(+) monocyte subsets. Compared to classical monocytes, CD16(+) monocytes are generally termed pro-inflammatory monocytes and play an important pathogenic role in autoimmune diseases...

Paclitaxel (PTX) which easily elutes into ascites is widely used to treat gastric cancer patients with peritoneal carcinomatosis (PC), but clinical outcomes are suboptimal. Increased concentrations of α1-acid glycoprotein (AGP), an important drug-binding protein, have been reported in the plasma and ascites of cancer patients. This study sought to clarify whether AGP binds to PTX and alters its anticancer effects. AGP concentrations were measured in the serum and ascites of gastric cancer patients with PC and in the serum of healthy volunteers...

Cryoglobulinemic vasculitis (CV) is a small-to-medium-vessel vasculitis that appears in 10-15 % of patients chronically infected with hepatitis C virus (HCV). The classic symptom triad of CV, purpura/asthenia/arthralgia, is accompanied by clinical features that include glomerulonephritis, neuropathy, interstitial pneumonitis, and cardiomyopathy, ranging in their severity from mild to life threatening. The risk of developing non-Hodgkin lymphoma is also higher. The cumulative 10-year survival rate of CV patients is significantly lower than in the age- and sex-matched general population, with death typically caused by nephropathy, malignancies, liver involvement, and severe infections...

Recently, the association of polymorphism rs1800562 (p.C282Y) in the hemochromatosis (HFE) gene with the increased risk of venous ulceration was shown. We hypothesized that HFE gene polymorphism might be involved not only in ulceration process, but also in susceptibility to primary varicose veins. We genotyped HFE p.C282Y (rs1800562) and p.H63D (rs1799945) variants in patients with primary varicose veins (n = 463) and in the control group (n = 754). In our study, p.282Y variant (rs1800562 A allele) was significantly associated with the risk of varicose veins (OR 1...

The presence of interval sentinel lymph nodes in melanoma is documented in several studies, but controversies still exist about the management of these lymph nodes. In this study, an immunohistochemical evaluation of tumor cell proliferation and neo-angiogenesis has been performed with the aim of establishing a correlation between these two parameters between positive and negative interval sentinel lymph nodes. This retrospective study reviewed data of 23 patients diagnosed with melanoma. Bioptic specimens of interval sentinel lymph node were retrieved, and immunohistochemical reactions on tissue sections were performed using Ki67 as a marker of proliferation and CD31 as a blood vessel marker for the study of angiogenesis...

Natriuretic peptides (NP) play a key role in regulation of salt and water balance. Corin, a serine protease which activates NP, plays a key role in regulation of blood pressure and cardiac function. The aim of the study was to evaluate the involvement of corin in renal physiopathology, analyze its levels in dialyzed patients and evaluate its relation with fluid overload and comorbidities such as heart failure and blood hypertension. We studied serum corin in uremic patients (n = 20) undergoing hemodialysis therapy (HD) and in healthy subjects (HS)...

Age-related changes in the immune system, commonly termed "immunosenescence," contribute to deterioration of the immune response and fundamentally impact the health and survival of elderly individuals. Immunosenescence affects both the innate and adaptive immune systems; however, the most notable changes are in T cell immunity and include thymic involution, the collapse of T cell receptor (TCR) diversity, an imbalance in T cell populations, and the clonal expansion of senescent T cells. Senescent T cells have the ability to produce large quantities of proinflammatory cytokines and cytotoxic mediators; thus, they have been implicated in the pathogenesis of many chronic inflammatory diseases...
