Abstract: A method for constructing stable bioactive fusion proteins of the difficult to express turn or necrosis factor superfamily (TNFSF), and particularly members CD40L (CD 154) and RANKL/TRANCE, with collectins, particularly pulmonary surfactant protein D (SPD) is described. Single trimers of these proteins lack the full stimulatory efficacy of the natural membrane forms of these proteins in many cases. The multimeric nature of these soluble fusion proteins enables them to engage multiple receptors on the responding cells, thereby, mimicking the effects of the membrane forms of these ligands. For CD40L-SPD, the resulting protein stimulates B cells, macrophages, and dendritic cells, indicating its potential usefulness as a vaccine adjuvant. The large size of these fusion proteins makes them less likely to diffuse into the circulation, thereby limiting their potential systemic toxicity.

Abstract: The present invention features methods for treatment or prevention of infection by intracellular pathogens (e.g., Mycobacterium species) by administration of an immunomodulatory nucleic acid molecule. In one embodiment, immunomodulatory nucleic acid molecule are administered in combination with another anti-pathogenic agent to provide a synergistic anti-pathogenic effect.

Abstract: A new, human proteinaceous lymphokine denominated cytotoxicity triggering factor (CTF) is disclosed as are methods of its preparation and use. Substantially pure CTF has an apparent M.sub.r of about 55 kd, is capable of inducing secretion of a tumor-killing factor containing tumor necrosis factor-alpha from primed monocytes, and is substantially free from pyrogen as well as interferon-gamma, interleukin-2 and direct cytotoxin.
