Dendritic cells (DCs)are the most potent antigen-presenting cells of the immune system, as such they are able to direct the immune system specifically against cancer cells. Currently DCs are used in clinical vaccination studies and immunological and clinical responses have been observed. For inducing anti-tumor immunity, the DCs have to be loaded with tumor antigen (i.e. molecular structures that are presented by the tumor, that are recognized by the immune system). Currently most studies use tumor peptides (small protein fragments) for this purpose. This approach has several disadvantages: only patients with a certain HLA-type can be treated and the immune response that is induced by the vaccine is limited to the used peptides. These disadvantages do not exist when the DCs present antigen which is endogenously processed, for example after RNA transfection. For this reason we investigate the immunogenicity of DCs that are pulsed with peptides or transfected with mRNA encoding melanoma associated antigens in stage III and IV melanoma patients.

This phase II, randomized, open-label trial aims to assess whether the vaccination increase RFS in disease free melanoma patients after surgery. Patients will be randomized between Intrade...
RATIONALE: Vaccines made from a person's dendritic cells and antigens may make the body build an immune response to kill tumor cells. PURPOSE: Phase I/II trial to study the effectiveness ...
RATIONALE: Vaccines made from a person's white blood cells and a donor's tumor cells may help the body build an effective immune response to kill tumor cells. PURPOSE: This phase II trial...
RATIONALE: Vaccines made from a person's dendritic cells mixed with tumor peptides and proteins may help the body build an effective immune response to kill tumor cells. Infusing the vacci...
The purpose of this study is to test a combined treatment using cyclophosphamide and a novel dendritic cell vaccine in patients with Stage IV melanoma.
The chemokine MIP3α (CCL20) binds to CCR6 on immature dendritic cells. Vaccines fusing MIP3α to gp100 have been shown to be effective in therapeutically reducing melanoma tumor burden and prolonging...
In the current era of checkpoint inhibitors, some patients with metastatic melanoma have shown a significant improvement in survival. However, optimization of immunotherapy is an ongoing effort. Monoc...
Management of stage IV melanoma patients remains a challenge. In spite of promising new therapies, many patients develop resistance and progression. The aim of this pilot study was to determine if CTC...
Recipients of autologous haemopoietic stem-cell transplants (auto-HSCT) have an increased risk of herpes zoster and herpes zoster-related complications. The aim of this study was to establish the effi...
Angioimmunoblastic T-cell lymphoma (AITL) is a rare form of NHL and usually presents in the late stage due to the atypical laboratory findings. Immunohistochemistry of the lymph node in AITL is charac...
A melanosome-specific protein that plays a role in the expression, stability, trafficking, and processing of GP100 MELANOMA ANTIGEN, which is critical to the formation of Stage II MELANOSOMES. The protein is used as an antigen marker for MELANOMA cells.
An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)
A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)
A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids. (From Dorland, 28th ed)
Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (Birbeck granules). They are found principally in the stratum spinosum of the EPIDERMIS and are rich in Class II MAJOR HISTOCOMPATIBILITY COMPLEX molecules. Langerhans cells were the first dendritic cell to be described and have been a model of study for other dendritic cells (DCs), especially other migrating DCs such as dermal DCs and INTERSTITIAL DENDRITIC CELLS.
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
