These are RCC patients with clear cell histology, treated using the PME-CD40L DC product. At present, 6 of the 12 patients that have been restaged using RECIST criteria have less tumor burden that when they enrolled in the study (15 weeks earlier).

Monocyte-derived and cocktail-matured DC electroporated with a combination of RNAs encoding tumor antigens (MelanA, Mage3, Survivin) and E/L-selectin are currently used in a clinical trial. Most patients having received the vaccine already demonstrated broad responses to numerous peptides prior vaccination. Significantly enhanced responses to several peptides and occurrence of new responses was seen in 6 patients, 5 of which were vaccinated with E/L-S+ DC. These data provide evidence for a superior immunopotency of E/L-selectin expressing DC.

An HIV infected individuals stable under HAART study has been initiated. These patients are being vaccinated with cytokine cocktail matured DCs electroporated with mRNA encoding Tat, Rev and Nef. The cDNA’s encoding these early expressed HIV antigens have been human codon optimized and modified with lysosomal targeting sequences. So far, 17 patients have been included in the study.

Aiming at finding possible reasons for the discrepancies between our findings and published data could be the amount of ONTAK used in patients, we filed an amendment to the clinical trial allowing the inclusion of additional 4 patients. These patients will receive higher doses (12microg/kg 3x and 18microg/kg 1x) before vaccination. Taking into account direct effects of ONTAK on DC, patients will be vaccinated some days after last ONTAK treatment (as soon as blood DC have recovered to 50% of pre ONTAK amount). Third stage of DERMA-ER-DC 05 clinical trial.

Four patients are enrolled in a clinical trial for vaccination with DC loaded with apoptotic leukemic cells. A strong type I T cell response has been induced. Preliminary data also indicate reduction of circulating tumor cells. No adverse effects have been observed.

These patients are taking part in a clinical study. They are patients that are successfully treated with highly active anti-retroviral therapy (HAART) with no measurable viral load AND have a cryopreserved infectious plasma sample that was drawn immediately prior to initiation of HAART. They are administered 4 monthly doses of the Arcelis product.

These 70 patients were evaluated in the DERMA-ER-DC 04 clinical trial of DC-based therapy of melanoma patients (multipeptide loaded cytokine matured moDC +/- CD40L activation). The analysis for the first time showed a clinical correlation of induced immune responses as measured in the blood with outcome, as there have been so far statistically significantly less events in stage III patients showing good CTL reponses (IFN-y Elispot) to multiple class I and II peptides compared to low responders of the stage III cohort. Additional in vitro maturation of DC by CD...

77 patients have been enrolled in two Phase III trials from 2 institutions testing dosing or duration of IM administration (EORTC 62005 and BFR14 trials).

These patients received multipeptide loaded cytokine matured moDC + prior Treg elimination by 3x ONTAK treatment [5µg/kg]; first phase of DERMA-ER-DC 05 trial.

These patients with Previously Treated B-cell Chronic Lymphocytic Leukemia are taking part in a clinical study and receive multiple injections of CLL-DCV01.

These patients receive a DC vaccine composed by autologous DCs electroporated with mRNA encoding CD40L, CD70, caTLR4 and one tumorantigen (gp100, Tyrosinase, Mage-C2 or Mage-A3).

The B-CLL patients were vaccinated with autologous, apoptotic, leukemic cells (Apo-DC). The first cohort of patients received the vaccine without additional adjuvants, while the next cohort of 5 patients who receive the vaccine with GM-CSF as an adjuvant. Clinical trial on vaccination of B-CLL patients with autologous, apoptotic, leukemic cells (Apo-DC), progressed further in 2007. Cohort 1 with the vaccine alone and cohort 2 (5 patients) combining the vaccine together with GM-CSF as an adjuvant has finished accrual and all patients in these two cohorts have ...

This colony of transgenic mice that over-express the rat HER-2/neu oncogene under the MMTV promoter were used to study new strategies of DC-based and other therapies for advanced breast cancer. Founders were provided by Forni, Torino IT.

These mice were used in a DC staining experiment. We have started to visualize and characterize the DC which carry I-Ad/LACK complexes at the cell surface in BALB/c mice infected by leishmania major.

These not immunized mice were used in a DC staining experiment. To investigate whether several mAb could be used to detect APC presenting LACK in vivo, BALB/c mice were immunized or not with either LACK or OVA. LN cells were purified 2 days later, and stained with either 2C44, 2F74, 2E60 or 2X8 mAb. None of these mAb stained DC purified from non immunized mice. However, among the 4 mAb, only 2C44 could stain DC in LACK-immunized mice, but not in OVA-immunized mice. Furthermore, 2C44 stained DC from LACK-immunized mice expressing the H2-d haplotype but did no...

These mice were immunized with OVA and used in a DC staining experiment. LN cells were purified 2 days later, and stained with either 2C44, 2F74, 2E60 or 2X8 mAb. None of these mAb stained DC purified from non immunized mice. However, among the 4 mAb, only 2C44 could stain DC in LACK-immunized mice, but not in OVA-immunized mice.

We have attempted to identify the antigen-presenting cells (APCs) that are responsible for the development of immune tolerance in mice that have been breast-fed by antigen-exposed lactating mothers. Recent experiments performed in our laboratory have shown that the exposure of a mother to an airborne antigen during lactation impacts asthma development in their progeny. We found that airborne allergens were efficiently transferred from the mother to the neonate through the milk and that this transfer resulted in the development of antigen-specific tolerance.

The yeast cells were resuspent in 3.6 ml AE Buffer and then transferred in 15 ml tubes wit 200 µl 10% SDS (w/v). 2 ml of preheated acid phenol (pH 4.3) were added and the falcon were mixed by vortex.

After 10’ of incubation in 65 °C water bath, the samples were incubated on ice.

These mice were studied with regard to responses to viral infections and compared to TLR K/O mice. We used the mouse pox virus Ectromelia and MVA-BN.
