    Several approaches to increase tumor cell immunogenicity and anti-tumor T-cell reactivity have been reviewed. In contrast to unspecific immune stimulation, the activation of specific T-cell reactivity can lead to long-lasting anti-tumor immunity. In several instances, immunization with modified tumor cells led to the induction of tumor immunity against the original non-modified tumor cells. In our own studies two types of approaches were also effective with the highly metastatic mouse tumor line ESb which carries a weak tumor associated antigen. Postoperative immunization with either virus modified ESb cells or with mutagenized variants of ESb cells led to the survival of a significant proportion of the treated animals. These animals had been cured of their micrometastases and developed long lasting anti-tumor immunity. It is hoped that such modified tumor cells could become useful reagents for tumor immunotherapy, especially in situations where the tumor burden is low. Future efforts should be directed towards testing the effectiveness of immunogenic modified tumor variants in combination with surgery or chemotherapy for treatment of micrometatases.

    The Tumor Microenvironment

    Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

    T Cell Activation and Clonal Selection

    T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

    Cytotoxic T Cells-mediated Immune Response

    Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
    Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
    Tumor Immunotherapy01:27

    Tumor Immunotherapy

    Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
    Cancer Vaccines01:30

    Cancer Vaccines

    Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
    Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
