1. NF-kB in epidermal signal transduction and tumor development
Sammanfattning : The transcription factor NF-kappaB has been extensively studied since its discovery. NFkappaB has been shown to be invoved in many cellular processes in many different cell types. However, its functions in skin physiology and epidermal tumor development are largely unknown. LÄS MER
2. The immunomodulatory properties of C-Med 100 an extract of the plant Uncaria tomentosa
Sammanfattning : Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. LÄS MER
3. Regulation of lymphocyte activation and death
Sammanfattning : T lymohocytes (T cells) and B lymphocytes (B cells) are important effector cells of the adaptive immune system. In response to infections, B cells are activated and produce antibodies against specific antigens. LÄS MER
4. The ups and downs of T cells The role of costimulatory molecules in the modulation of T cell responses
Sammanfattning : T cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. LÄS MER
5. Methods for Preclinical Evaluation of Cytotoxic Drugs : With Special Reference to the Cyanoguanidine CHS 828 and Hollow Fiber Method
Sammanfattning : The novel cyanoguanidine CHS 828 has shown promising antitumor activity in many in vitro and in vivo studies. The long-term 14 days in vitro hollow fiber cultures, where tumor cells from different tumor cell lines were cultured inside semipermeable fibers, were more resistant to CHS 828 and other cytotoxic drugs than the shorter-term 3 days cultures.
