AIM OF THE STUDY: Lymphomas are a heterogeneous group of tumours of lymphoid tissue in which there is an abnormal proliferation of cells of the lymphatic system. The literature notes a gradual increase in the incidence of this type of cancer in the whole population. The aim of the study was to evaluate whether the above tendency occurs in the head and neck area. MATERIAL AND METHODS: In the years 2005-2014, at the Otolaryngology and Laryngological Oncology Department of the Upper Silesian Medical Centre in Katowice, 77 cases of lymphoma were recorded, 58 of which were analysed in terms of location, histological type, age and sex of the patient, and the presence of risk factors...

To prime adaptive immune responses from the female reproductive tract (FRT), particulate antigens must be transported to draining lymph nodes (dLNs) since there are no local organized lymphoid structures equivalent to those found in the respiratory or gastrointestinal tracts. However, little is known about how to safely and effectively navigate successive barriers to transport such as crossing the epithelium and gaining access to migratory cells and lymphatic drainage that provide entry into dLNs. Here, we demonstrate that intravaginal pre-treatment with chitosan significantly facilitates translocation of nanoparticles (NPs) across the multilayered vaginal epithelium to target dLNs...

Ivermectin is an endectocide that has been used broadly in single dose community campaigns for the control of onchocerciasis and lymphatic filariasis for more than 30 years. There is now interest in the potential use of ivermectin regimens to reduce malaria transmission, envisaged as community-wide campaigns tailored to transmission patterns and as complement of the local vector control programme. The development of new ivermectin regimens or other novel endectocides will require integrated development of the drug in the context of traditional entomological tools and endpoints...

BACKGROUND: Adipose tissue-derived stem cells (ASCs) have been investigated as therapeutic tools for a variety of autoimmune diseases, including inflammatory diseases. However, the mechanisms underlying the immunomodulatory properties of ASCs are not well understood. Here, we investigated the mechanism of regulatory T cell (Treg) induction in ASC therapy in a murine model of inflammatory bowel disease. METHODS: Acute colitis was induced in mice using dextran sulfate sodium and ASCs administered intraperitoneally...

Obesity and associated pathologies are a dramatically growing problem. New therapies to prevent and/or cure them are strongly needed. Adipose tissue is a logical target for pharmacological intervention, since it is now recognized to exert an important endocrine function, secreting a variety of adipokines affecting, for example, adiposity and insulin resistance. This proof of principle work focuses on the development of novel lipid-mimetic prodrugs reaching fat deposits by the same lymphatic absorption route followed by dietary triglycerides...

NKG2D, an activating receptor expressed on CD8(+) T lymphocytes, serves as a co-stimulation molecule by engagement with its ligands MICA/B and ULBPs to trigger immune activation against tumors. Currently, the biological function and clinical significance of NKG2D in gastric cancer remains unexplored. The study aims to investigate the expression of NKG2D in gastric cancer in association with clinical prognosis and its biological function. Real-time PCR was used to analyze NKG2D expression in paired cancer and adjacent non-malignant tissues in 139 gastric cancer patients between 2007 and 2010 in Shanghai Cancer Center...

Humanized mice engrafted with human hematopoietic stem cells and developing functional human T-cell adaptive responses are in critical demand to test human-specific therapeutics. We previously showed that humanized mice immunized with long-lived induced-dendritic cells loaded with the pp65 viral antigen (iDCpp65) exhibited a faster development and maturation of T cells. Herein, we evaluated these effects in a long-term (36 weeks) nonclinical model using two stem cell donors to assess efficacy and safety. Relative to baseline, iDCpp65 immunization boosted the output of effector memory CD4(+) T cells in peripheral blood and lymph nodes...

Human lymphatic filariasis, the parasitic disease caused by the filarial nematodes Wuchereria bancrofti, Brugia malayi, and Brugia timori, is ranked as the second most complex clinical condition leading to permanent and long-term disability. The multiple antigen peptide (MAP) approach is an effective method to chemically synthesize and deliver multiple T and B cell epitopes as the constituents of a single immunogen. Here, we report on the design, chemical synthesis, and immunoprophylaxis of three epitopes that have been identified from promising vaccine candidates reported in our previous studies, constructed as MAP on an inert lysine core for human lymphatic filariasis in Jird model...

OBJECTIVES: Sentinel lymph node (SLN) mapping is currently a routine technique in breast cancer management and preoperative scintigraphic imaging plays a crucial role in the process of SLN detection. The guidelines recommend performing planar acquisition and optional single-photon emission tomography/computed tomography (SPECT/CT) imaging. The aim of this study was to verify whether routine performing of SPECT/CT in addition to planar imaging increases the sensitivity of SLN detection in patients with early-stage breast cancer...

Nanoparticles (NPs) have undergone extensive investigation as drug delivery and targeting vehicles. NP delivery is often via the parenteral route, reliant on administration using hypodermic needles, which can be associated with patient compliance issues and safety concerns. In the recent past, the intradermal delivery of NPs, via novel dissolving microneedle (MN) arrays has garnered interest in the pharmaceutical community. However, published studies using this combinatorial approach have been limited, in that they have focussed on the use of in vitro and ex vivo models only...

Recent studies in tumor homing peptides have shown the specificity of LyP-1 (CGNKRTRGC) to tumor lymphatics. In this present work, we evaluated the possible interactions between cyclic LyP-1 and its receptor, p32, with molecular dynamics and docking studies in order to lead the design of novel LyP-1 derivatives, which could bind to p32 more effectively and perform enhanced antitumor effect. The total binding enthalpy energies have been obtained by MM-PBSA thermodynamic computations and the favorability of p32...

Placental growth factor (PlGF), a proangiogenic member of vascular endothelial growth family, is active during pathological conditions like cancer, metastasis formation and hind limb ischemia and in wound healing. Endothelial cells express PlGF and hypoxia positively modulates in vitro its expression. To verify whether hypoxia modulates PlGF expression in different cellular contexts and in vivo, we first analyzed five human and five mouse cancer cell lines showing that in eight of them hypoxia positively modulates PlGF...
