INTRODUCTION: Recently, it has been shown that hematological parameters may be used as markers of inflammatory response. In this study, the authors aimed to identify the potential roles of the neutrophil-lymphocyte ratio (NLR) and other hematological markers in the evaluation of hidradenitis suppurativa (HS), a chronic, recurrent inflammatory disease. MATERIALS AND METHODS: A total of 35 patients, diagnosed with HS between January 1, 2012 and December 31, 2014, were categorized into 3 groups according to the Hurley staging system...

Despite substantial experimental and epidemiological research, there is limited knowledge of the uranium-induce health effects after chronic low-dose exposures in humans. Biological markers can objectively characterize pathological processes or environmental responses to uranium and confounding agents. The integration of such biological markers into a molecular epidemiological study would be a useful approach to improve and refine estimations of uranium-induced health risks. To initiate such a study, Concerted Uranium Research in Europe (CURE) was established, and involves biologists, epidemiologists and dosimetrists...

Pilosebaceous unit occlusion and secondary inflammatory perifollicular lympho-histiocytic infiltration seem to be the underlying etiopathogenic mechanisms giving rise to hidradenitis suppurativa (HS). Increased levels of tumor necrosis factor (TNF)-alpha and other cytokines such as interleukins 12 and 23 (IL12/23) and interleukins 10 and 17 have been observed in HS lesional skin. Biological drugs have been reported to be effective for HS, but the level and duration of the response are quite variable. Among anti-TNF drugs, adalimumab and infliximab are the drugs that seem to obtain better results in HS...

Posttransplant lymphoproliferative disorders are a spectrum of lymphoproliferative disorders seen in recipients of solid-organ, bone marrow, and stem cell allografts. They include polyclonal early lesions mimicking infectious mononucleosis and monoclonal proliferations of B and T cells, indistinguishable from lymphomas occurring in immunocompetent individuals. Although most posttransplant lymphoproliferative disorders are B-cell neoplasms, T-cell posttransplant lymphoproliferative disorders are very rare. Among solid-organ transplants, renal allografts have low risk for development of posttransplant lymphoproliferative disorders...

The alkylating agent melphalan is used in the treatment of hematological malignancies, especially multiple myeloma. In the past, the usefulness of melphalan has been solely attributed to its cytotoxicity on fastgrowing cancerous cells. Although the immunomodulatory effects of melphalan were suggested many years ago, only recently has this aspect of melphalan's activity begun to be elucidated at the molecular level. Emerging evidence indicates that melphalan can foster an immunogenic microenvironment by inducing immunogenic cell death (ICD) as characterized by membrane translocation of endoplasmic reticulum protein calreticulin (CRT) and by release of chromatin-binding protein high-mobility group box 1 (HMGB1)...

Chronic lipopolysaccharide (LPS) exposure to mice reduces the lymphoid compartment and skews the hematopoietic cell compartment toward myeloid-cells, which is considered to be a direct effect of LPS on hematopoietic stem cells. However, the effect of chronic LPS exposure on stromal-cells, which compose the hematopoietic microenvironment, has not been elucidated. Here, we investigated early- and late-phase effects of repeated LPS exposure on stromal-cells. During the early phase, when mice were treated with 5 or 25 µg LPS three times at weekly intervals, the numbers of myeloid-progenitor (colony forming unit-granulocyte macrophage (CFU-GM)) cells and B lymphoid-progenitor (CFU-preB) cells in the bone-marrow (BM) rapidly decreased after each treatment...

We studied acute myeloid leukemia (AML) patients with lympho-myeloid clonal hematopoiesis (LM-CH), defined by the presence of DNA methyltransferase 3A (DNMT3A) mutations in both the myeloid and lymphoid T-cell compartment. Diagnostic, complete remission (CR) and relapse samples were sequenced for 34 leukemia-related genes in 171 DNMT3A mutated adult AML patients. AML with LM-CH was found in 40 patients (23%) and was associated with clonal hematopoiesis of indeterminate potential years before AML, older age, secondary AML and more frequent MDS-type co-mutations (TET2, RUNX1 and EZH2)...

The survival rates of gastric cancer patients with cytology-positive peritoneal lavage fluid without macroscopic dissemination (CY+/P-) is the same as that of patients with overt peritoneal metastasis.The 5-year survival rate of such patients is only 2%. The current study aims to highlight its significance in the staging of gastrointestinal malignancies and its implications for patient care. Prospective nonrandom analysis of peritoneal wash cytology in patients with gastrointestinal malignancies was conducted in the department of Surgical Gastroenterology, Nizams Institute of Medical Sciences, Hyderabad from January 2012 to June 2013...

Recently we reported the development of 100nm polyglutamic acid (PGA)-based nanocapsules, which were intended to carry anticancer drugs to the lymphatic system (Abellan-Pose et al., 2016). In this work, the objective was to further assess the potential "lympho-targeting" properties of radiolabeled (111)In-PGA and (111)In-PGA-PEG, following intravenous or subcutaneous administration. The results indicate that, following intravenous administration, both types of nanocapsules exhibit a modest accumulation in the lymph nodes (⩽2...

Atopic dermatitis (AD) is a common inflammatory skin disorder. Chronic AD lesions present hyperkeratosis, indicating a disturbed desquamation process. KLK7 is a serine protease involved in the proteolysis of extracellular corneodesmosome components, including desmocollin 1 and corneodesmosin, which leads to desquamation. KLK7 is secreted by lamellar granules and upregulated in AD lesional skin. However, despite increased KLK7 protein levels, immunostaining and electron microscopy indicated numerous corneodesmosomes remaining in the uppermost layer of the stratum corneum from AD lesions...

Protease regulation plays a crucial role in skin homeostasis and inflammation as revealed by the identification of loss-of-function mutations in SPINK5 (serine protease inhibitor of Kazal type 5) in Netherton sydrome (NS). SPINK5 encodes LEKTI (lympho-epithelial Kazal type related inhibitor), a multi-domain serine protease inhibitor expressed in all stratified epithelia. Our laboratory has developed a number of murine models which have been instrumental to dissecting the pathogenesis of NS. This mini-review discusses the major findings of these models and emphasizes the role of protease regulation, especially Kallikrein related peptidases in NS...

The final stages of restriction to the T cell lineage occur in the thymus after the entry of thymus-seeding progenitors (TSPs). The identity and lineage potential of TSPs remains unclear. Because the first embryonic TSPs enter a non-vascularized thymic rudiment, we were able to directly image and establish the functional and molecular properties of embryonic thymopoiesis-initiating progenitors (T-IPs) before their entry into the thymus and activation of Notch signaling. T-IPs did not include multipotent stem cells or molecular evidence of T cell-restricted progenitors...

Tissues that require a great supply of nutrients and possess high metabolic demands, such as lympho-hemopoietics tissues, are the first to be affected by protein malnutrition (PM). Thus, PM directly affects hemopoiesis and the production and function of immune cells. Consequently, malnourished individuals are more susceptible to infections. Mesenchymal stem cells (MSCs) have immunomodulatory properties and are important in the formation of lympho-hemopoietic stroma. Since an adequate supply of nutrients is essential to sustain stroma formation, which is mainly constituted of MSCs and differentiated cells originated from them, this study investigated whether PM would influence some biological and immunomodulatory aspects of MSCs...

Lymphatic vasculature drains interstitial fluids, which contain the tissue's waste products, and ensures immune surveillance of the tissues, allowing immune cell recirculation. Until recently, the CNS was considered to be devoid of a conventional lymphatic vasculature. The recent discovery in the meninges of a lymphatic network that drains the CNS calls into question classic models for the drainage of macromolecules and immune cells from the CNS. In the context of neurological disorders, the presence of a lymphatic system draining the CNS potentially offers a new player and a new avenue for therapy...

This is a case report of de novo development of two cerebral cavernous malformations adjacent to existing developmental venous anomalies. The development of cavernomas was noted over a follow-up period of 10 years. These developments happened during the course of staged endovascular management of a complex dural arterio-venous fistula along the right sphenoid wing. The patient presented with a proptosis secondary to lympho-haemangiomatous lesion of the fronto-orbital region and a high-flow right sphenoid wing dural arterio-venous fistula...
