PURPOSE As compared with natural tumor peptide sequences, carefully selected analog peptides may be more immunogenic and thus better suited for vaccination. However, T cells in vivo activated by such altered analog peptides may not necessarily be tumor specific because sequence and structure of peptide analogs differ from corresponding natural peptides. EXPERIMENTAL DESIGN Three melanoma pati...

Aberrant antigens expressed by tumor cells, such as in melanoma, are often associated with humoral immune responses, which may in turn influence tumor progression. Despite recent data showing the central role of adaptive immune responses on cancer spread or control, it remains poorly understood where and how tumor-derived antigen (TDA) induces a humoral immune response in tumor-bearing hosts. B...

Lymphatic vessels in the tumor microenvironment are known to foster tumor metastasis in many cancers, and they can undergo activation, hyperplasia, and lymphangiogenesis in the tumor microenvironment and in the tumor-draining lymph node. The mechanism underlying this correlation was originally considered as lymphatic vessels providing a physical route for tumor cell dissemination, but recent st...

In cancer patients, the removal of tumor-draining lymph nodes during tumor resection can lead to acquired lymphedema. This disease, which is characterized by tissue swelling and increased risk of infection due to restricted lymph flow, lacks an effective treatment. Limitations to the design and conduct of randomized trials to date have limited the evaluation of proposed surgical techniques. As ...

The UV radiation in sunlight is the primary cause of skin cancer. UV is also immunosuppressive and numerous studies have shown that UV-induced immune suppression is a major risk factor for skin cancer induction. Previous studies demonstrated that dermal mast cells play a critical role in the induction of immune suppression. Mast cell-deficient mice are resistant to the immunosuppressive effects...

granulomatous response in association with breast cancer and within the cancer draining lymph nodes is an extremely rare phenomenon. granulomatous inflammation is an immune response commonly seen against infectious agents and certain non-neoplastic conditions. the etiopathogenesis of granulomas associated with malignancies is not clear but it may be because of an immunologic reaction to tumour ...
