Dendritic Cell Vaccines
Dendritic Cell Vaccines in Pediatric Immunotherapy
Key Points:
- Dendritic cells (DCs) are professional antigen-presenting cells crucial for initiating and modulating immune responses
- DC vaccines represent a personalized immunotherapy approach using patient's own immune cells
- Primary applications include treatment of pediatric cancers and immunodeficiencies
- Success rates vary by condition but show promising results in neuroblastoma and brain tumors
Fundamental Concepts
Dendritic cell vaccines represent a breakthrough in personalized immunotherapy for pediatric patients. These specialized therapeutic agents are created using the patient's own dendritic cells, which are harvested, modified ex vivo, and reintroduced to stimulate specific immune responses against disease targets.
Immunological Basis:
- Recognition and processing of antigens
- Presentation to T cells via MHC molecules
- Activation of both innate and adaptive immunity
- Generation of memory responses
Clinical Applications in Pediatrics
Primary Indications:
- Pediatric Cancers
- Neuroblastoma
- Brain tumors
- Leukemia
- Sarcomas
- Immunodeficiency Disorders
- Primary immunodeficiencies
- Secondary immune dysfunction
Patient Selection Criteria:
- Age considerations (typically >6 months)
- Immune system status
- Disease stage and previous treatments
- Availability of target antigens
