36. Immunotherapy in cancer and HIV
Abstract : Two major threats to human health are cancer and human immunodeficiency virus (HIV) infection. In both cases, a feature of progress of the disease is a defective immune function. Immunological mechanisms have evolved whereby transformed cells and HIV-1 infected cells avoid recognition and elimination by the immune system. READ MORE

37. Organic dust from pig environment induces activation of human T cells
Abstract : Farmers suffer more frequently from inflammatory airway disorders than the population in general and a ongoing airway inflammation has been shown also in symptom-free healthy farmers. Exposure in a swine confinement building causes an intense airway inflammation with recruitment of inflammatory cells, predominately neutrophils, in healthy, previously, non-exposed subjects.

38. HLA and KIR gene polymorphism in hematopoietic stem cell transplantation
Abstract : The major histocompatibility complex (MHC) in humans known as the Human Leukocyte Antigens (HLA) is localised to the short arm of chromosome six. The HLA class 1 antigens, HLA-A, -B and -C are highly polymorphic glycoproteins expressed on the cell surface of most nucleated cells in the body. READ MORE

39. Studies of the recognition and activation of natural killer cells
Abstract : Natural killer (NK) cells mediate part of the innate immune response that impedes the spread of invading microorganisms and shapes the downstream adaptive immune response. NK cells spontaneously kill tumor cells and other cells upon contact. Killing requires engagement of germline encoded receptors that mediate positive and negative signals. READ MORE

40. Modulation of natural killer cell and T-cell functions by CD94/NKG2A receptors
Abstract : Natural Killer (NK) cells constitute a subset of lymphocytes capable of cytokine production and/or cellular cytotoxicity. Although NK cells can be activated experimentally by a multitude of agents, the in vivo mechanisms of activation and regulation are not fully elucidated. READ MORE
