Metastatic Cell Adhesion:

Researchers at the Institute for Molecular Medicine have found that multiple adhesive mechanisms are responsible for malignant cell adhesion to microvessel endothelial cells and to underlying subendothelial matrix, and they have begun to identify and isolate the receptors responsible. In some cases, this has led to the isolation, sequencing and identification of new cell surface components. These studies are being extended into an examination of the role of integrins and nonintegrin adhesion components in the adhesion of metastatic cells to specific microvessel endothelial cells that have been established in culture and characterized.

Metastatic Cell Migration:

An important property of highly metastatic cells is their ability to respond to paracrine and autocrine motility factors. Scientists at the Institute for Molecular Medicine were among the first to have isolated and studied these factors. Concentrating on soluble paracrine factors, such as those from organ-derived microvessel endothelial cells, the first paracrine motility factor was isolated and characterized from hepatic sinusoidal endothelial cells. Sequence data indicate that this factor is related to complement component C3b. A different motility factor has been isolated from lung microvessel endothelial cells, and sequence analysis of this factor indicates that it is a known macrophage motility factor (MCP-1). Other factors are being characterized from different organ-derived fibroblast and parenchymal cells.

Metastatic Cell Invasion:

To extravasate, metastatic cells must penetrate basement membranes and stromal matrix using a battery of degradative enzymes. We have identified and purified new enzymes involved in this process, including heparanase and an aminopeptidase of 29 kDa in size. Scientists at The Institute for Molecular Medicine are studying matrix metalloproteinases, endoglycosidases and other proteases and their role in metastatic cell invasion and growth. We are also studying the role of organ-derived paracrine factors in regulating the synthesis of certain degradative enzymes in host tissues and cancer cells. For example, it was found that nerve growth factor can stimulate the invasion of brain-metastatic melanoma cells by increasing the synthesis of degradative enzymes.

Metastatic Cell Growth:

Scientists at the Institute for Molecular Medicine were the first to identify and purify paracrine growth factors that differentially stimulate the growth of highly metastatic cells. A prominent growth factor was found to be released from endothelial cells and found to be highly homologous to transferrin. The gene of this factor is being cloned and studied. We have also found that fibroblasts and mast cells isolated from different organs release different amounts of various growth factors that can differentially stimulate the growth of highly metastatic cells.

Cellular Immunology of Cancer and Chronic Diseases:

The Institute has been involved in the development of DNA vaccine technology for generation of humoral and cellular immune responses against foreign and modified self-antigens. We have recently focused on developing DNA vaccines against different viral, tumor, bacterial, and other antigens. The significant advantage of DNA immunization is that it offers the capability to modify genes encoding desired antigen(s) to change the cellular localization of an antigen by adding or removing signal sequences or transmembrane domains and to target the desired type of immune response (humoral or cellular). More specifically, we have constructed DNA vaccines that encode not only an appropriate immunogen but also a special molecular adjuvant (molecules that stimulate the immune system, such as costimulatory molecules or cytokines) to direct immunity towards either antibody production (Th1 type of response) or cellular immune responses (Th2 responses). Employing this multiple gene technology approach we generated humoral immune response in an Alzheimer’s disease (AD) mouse model and cellular response in breast cancer mouse model.

Alzheimer’s Disease mouse model:
Recently, immunotherapy as a possible treatment for Alzheimer’s Disease (AD) has received considerable attention. It has been demonstrated that active or passive immunization of APP transgenic (APP/Tg) mice significantly reduced amyloid plaque deposition, neuritic dystrophy, and astrogliosis in APP/Tg mouse models of AD. Th1-type immune responses have been implicated in many autoimmune disorders, whereas Th2-type responses have been shown to inhibit autoimmune disease. Accordingly, it was suggested that Th2 type of humoral immune responses would be more beneficial in case of AD immunotherapy. Recently, we have analyzed the role of different adjuvants in the generation of B, Th1, and Th2 immune responses to immunization with fibrillar A42. Both the magnitude and the type of the immune response were affected by the choice of adjuvant. To generate anti-A humoral immune responses without the limitations of direct peptide and conventional adjuvant delivery, a plasmid DNA encoding A? fused with IL4 was generated and a potent Th2 type of immune responses was induced.

Breast cancer mouse model:
There are three major mechanisms whereby tumors escape immune recognition: (i) poor immunogenicity, when tumor cells lack expression of peptide:MHC ligands, adhesion molecules, and/or B7 (CD80/CD86) costimulatory molecules; (ii) antigenic modulation by antibodies; (iii) tumor-induced immune suppression by factors secreted by tumor cells (for example, TGFb). Published results support the presence of reactive T-cell clones specific to MUC1 breast cancer specific antigen, which are functionally inactive in the MUC1 transgenic mice (MUC1/Tg) because the lack of expression of B7 costimulatory molecules. More importantly, using the more potent B7 signal several authors have abrogated this tolerance. In an attempt to maximize the anti-tumor immune responses, we developed a plasmid vaccine that encodes MUC1 self-antigen and CD80 or CD86 costimulatory molecules. Only co-delivery of MUC1 vaccine and CD80 or CD86 to syngeneic mice induces protection against the challenge with breast cancer cells (4T1/2 subline of breat carcinoma line 410.4).

In addition to immune based strategies, we have also focused on analyzing of mechanisms of generation of Th1 or Th2 type of immune responses, including generation of cytotoxic lymphocytes and antibodies against self or altered self molecules.
