CpG-Loaded Multifunctional Cationic Nanohydrogel Particles as Self-Adjuvanting Glycopeptide Antitumor Vaccines
2014
Self-adjuvanting antitumor vaccines by multifunctional cationic nanohydrogels loaded with CpG. A conjugate consisting of tumor-associated MUC1-glycopeptide B-cell epitope and tetanus toxin T-cell epitope P2 is linked to cationic nanogels. Oligonucleotide CpG complexation enhances toll-like receptor (TLR) stimulated T-cell proliferation and rapid immune activation. This co-delivery promotes induction of specific MUC1-antibodies binding to human breast tumor cells without external adjuvant.
Monophosphoryl lipid A coating of hydroxyethyl starch nanocapsules drastically increases uptake and maturation by dendritic cells while minimizing th…
2015
Enhancing delivery of antigens to dendritic cells (DCs) is essential for the induction of vigorous antigen-specific cellular immune responses. Aim of the present study was to evaluate the properties of hydroxyethyl starch nanocapsules (HES-NCs) functionalized with anti-CD40, anti-DEC205, interferon-γ (IFNγ) and/or monophosphoryl lipid A (MPLA) with respect to the overall uptake, the released cytokine profile, and the influence on phenotypic maturation of human monocyte-derived DCs using flow cytometry, confocal microscopy and enzyme-linked immunosorbent assays. NC uptake by DCs was significantly enhanced by functionalizing NCs with anti-CD40 or MPLA. With respect to the cytokine profile and…
Characterization of the Adjuvant Effect of IL-12 and Efficacy of IL-12 Inhibitors in Type II Collagen-Induced Arthritis
1996
A destructive joint disease can be induced in susceptible DBA/1 mice by immunization with type II collagen emulsified with oil and either killed Mycobacterium tuberculosis or IL-12 as adjuvant. Cellular and humoral anti-collagen immune mechanisms appear to be involved in the pathogenesis of arthritis. We have characterized the adjuvant effect or IL-12 in more detail and addressed the question whether mycobacteria might act via the induction of endogenous IL-12. Injections of IL-12 into collagen-immunized DBA/1 mice promoted the development of IFN-gamma-producing CD4+ T cells and strongly upregulated the production of complement-fixing IgG2a and IgG2b antibodies resulting in severe arthritis…
Compliance and arthralgias in clinical therapy (COMPACT): Assessment of the incidence of arthralgia, therapy costs, and compliance in the first year …
2012
e11040^ Background: Aromatase Inhibitors (AI) are well established as adjuvant endocrine treatment for postmenopausal women with HR+ early breast cancer (EBC). However, clinical trial data show higher frequently of arthralgia with AI than tamoxifen. As arthralgia may be greatly influencing compliance to adjuvant therapy, we designed a prospective trial to collect real world data on the effects of AI-associated arthralgia on patient compliance, patient outcomes and treatment costs of arthralgia. Methods: COMPACT is an open, prospective non-interventional study (NCT00857012) assessing the incidence of arthralgia, therapy costs, and compliance within the first year of adjuvant anastrozole (AN…
Modulation of type II collagen-induced arthritis in DBA/1 mice by intravenous application of a peptide from the C1q-A chain.
1992
In this report we are able to show that intravenous (i.v.) application (day 0) of a nonapeptide (residues 26-34) from the human C1q A-chain (designated peptide A-C1q) prior to intradermal (i.d.) administration of chicken type II collagen (CII) in arthritis-susceptible DBA/1 mice (H2q), leads to abrogation of polymorphonuclear neutrophil (PMN) invasion into the joints. This nonapeptide exhibits epitope characteristics and high homology to residues 137-147 of CB11 (a cyanogen bromide fragment of chicken CII, known to contain both arthritis inducing and suppressing determinants). Arthritis index was lowest in animals pretreated i.v. with CII (as internal control), though animals pretreated i.v…
COMPliance and Arthralgia in Clinical Therapy: the COMPACT trial, assessing the incidence of arthralgia, and compliance within the first year of adju…
2014
5 Office-based Professional Association Gynecologic Oncologists e.V. in Germany (BNGO e.V.), Berlin; 6 Background: This prospective study evaluated the relationship between arthralgia and compliance during the first year of adjuvant anastrozole therapy in postmenopausal women with hormone receptor-positive early breast cancer. Patients and methods: COMPliance and Arthralgia in Clinical Therapy (COMPACT) was an open-label, multicenter, noninterventional study conducted in Germany. Patients had started adjuvant anastrozole 3-6 months before the study start. The primary end points were arthralgia, compliance, and the relationship between compliance and arthralgia, assessed at specific time poi…
Chemopreventive and Anticancer Role of Resveratrol against Oral Squamous Cell Carcinoma
2023
Oral squamous cell carcinoma (OSCC) is one of the most prevailing and aggressive head and neck cancers, featuring high morbidity and mortality. The available conventional treatments suffer from several adverse effects and are often inefficient in terms of their survival rates. Thus, seeking novel therapeutic agents and adjuvants is of the utmost importance for modern society. Natural polyphenolic compounds have recently emerged as promising chemopreventive and anticancer agents. Specifically, the natural compound resveratrol (RSV) has recently gained momentum for this purpose. RSV is useful for treating OSCC due to its antiproliferative, antimetastatic, and proapoptotic effects. Additionall…
Destroying the Shield of Cancer Stem Cells: Natural Compounds as Promising Players in Cancer Therapy
2022
In a scenario where eco-sustainability and a reduction in chemotherapeutic drug waste are certainly a prerogative to safeguard the biosphere, the use of natural products (NPs) represents an alternative therapeutic approach to counteract cancer diseases. The presence of a heterogeneous cancer stem cell (CSC) population within a tumor bulk is related to disease recurrence and therapy resistance. For this reason, CSC targeting presents a promising strategy for hampering cancer recurrence. Increasing evidence shows that NPs can inhibit crucial signaling pathways involved in the maintenance of CSC stemness and sensitize CSCs to standard chemotherapeutic treatments. Moreover, their limited toxici…
Adjuvant capecitabine in triple negative breast cancer patients with residual disease after neoadjuvant treatment: real-world evidence from CaRe, a m…
2023
BackgroundIn triple negative breast cancer patients treated with neoadjuvant chemotherapy, residual disease at surgery is the most relevant unfavorable prognostic factor. Current guidelines consider the use of adjuvant capecitabine, based on the results of the randomized CREATE-X study, carried out in Asian patients and including a small subset of triple negative tumors. Thus far, evidence on Caucasian patients is limited, and no real-world data are available.MethodsWe carried out a multicenter, observational study, involving 44 oncologic centres. Triple negative breast cancer patients with residual disease, treated with adjuvant capecitabine from January 2017 through June 2021, were recrui…
Efficacy of one-year maintenance in early adjuvant chemotherapy for intermediate risk non-muscle-invasive bladder cancer. Preliminary results of a ra…
2008
Introduction and Objective: The clinical value of early intravesical adjuvant chemotherapy after TUR of intermediate risk non-muscle-invasive bladder cancer (NMI TCCB) is well established. On the other hand, the optimal schedule regimen and the role of maintenance are still debated. The aim of the present study was to evaluate the effectiveness of one-year maintenance schedule in patients submitted to TUR plus adjuvant early intravesical chemotherapy. Methods: Between May 2002 and August 2003, 577 patients, were recruited. All patients underwent TUR and early (within 6 hours) intravesical chemotherapy with epirubicin at the dose of 80 mg diluted in 60 ml of saline solution. When histology w…
