The present invention relates to a spray-dried composition comprising as an active ingredient at least one member protein of the collectin family or its functional equivalent for treating and preventing microbial infectious diseases. The present invention also relates to a method for producing the same composition. The composition produced by the method of the present invention is effective in suppressing infections caused by viruses, bacteria, fungi, and parasites. Since the composition is developed in a form suitable for inhalation, it can directly provide the active ingredient to the sites of infection from these microbes, and thus treat and prevent respiratory infections and external wounds.

A method of treating microbial infections, which consists of the steps of sequentially and repeatedly irradiating the microbe with continuous or pulsed infrared radiation and continuous or pulsed cooling such that heat and cold alternatively penetrates to the site of the infection in order to inactivate the pathogen.

Treatments are disclosed for inflammatory, autoimmune, or other disorders characterized by excessive activity of calprotectin, a protein that normally defends against microbial infections by sequestering available zinc, at a site of infection. Excessive calprotectin activity, which can cause zinc deficiencies in localized tissues, can create or aggravate various disorders. However, ingestion of systemic (oral) zinc supplements tends to activate offsetting mechanisms, and such supplements therefore usually are ineffective. Accordingly, targeted treatments are disclosed herein for suppressing and controlling excessive calprotectin activity, in local tissues. Such methods include targeted injections of zinc solutions, and plasmapheresis treatment. Screening tests also are described for identifying non-protein drugs that can either (i) bind specifically to the zinc-binding sites of calprotectin, or (ii) suppress the release of calprotectin by neutrophil cells.

The invention discloses application of autovaccine preparation containing TGF beta 1. Adjuvant is added in the autovaccine preparation to prepare medicinal preparation for treating continuous pathogen infection of livestock. The vaccine preparation is fusion protein obtained by the way that part or total of the TGF beta 1 or part or total of mutant or total of similar gene sequences is recombined with at least one helper T cell capable of improving immunogenicity or the gene sequence of carrier protein to construct eukaryon or pronucleus expression plasmid and transform host cell for expression, or is directly prepared by eukaryon expression plasmid obtained by construction. The vaccine preparation can be directly used for preparing medicinal preparation for treating the continuous pathogen infection of livestock, induce domestic animals to generate antibody capable of neutralizing self TGF beta 1, and remove immunodepression function caused by too high level of TGF beta 1 in continuous process of infection; simultaneously, the vaccine preparation can depress the generation of inducible regulatory T cell at the persistent infection part of an organism, thus being beneficial to breaking the immune tolerance state of in-vivo pathogen by the organism and promoting the removing function of the organism on the continuously infectious pathogen.

This invention relates to methods and compositions for diagnosis and treatment of chronic inflammatory diseases by blocking CD147 interaction with extracellular cyclophilin. Specifically, the methods and compositions of this invention regulate recruitment of leukocyte to the infection site by specifically blocking the CD147 domain involved with the chemotactic function without blocking the CD147 domain involved with EMMPRIN function.

Neutrophils (PMN) can migrate along gradients of chemoattractants across endothelial monolayers to sites of inflammation and infection. This chemotaxis through endothelial cell borders is involved in several acute and chronic inflammatory diseases, however our understanding of the role of endothelial second messengers in the regulation of leukocyte emigration is still incomplete. We investigated this using an in vitro model of neutrophil migration across human umbilical vein endothelial cells (HUVECs) and human microvascular endothelial cells (HMECs) on cell culture inserts. We report that activation of endothelial protein kinase C (PKC) by both phorbol myristate acetate (PMA) and Bryostatin-1 (a potent PKCδ and c activator) can completely abolish neutrophil migration mediated by both endothelial TNF-α stimulation and a leukotriene B4 (LTB₄) gradient. PMA protected against LTB₄ induced PMN transmigration for at least 24 hours in HMECs and HUVECs. Bryostatin-1 protected PMN migration for at least 24 hours in HMECs and at least 48 hours in HUVECs. Pretreatment with Go-6983 (PKCα, β, and δ inhibitor) before the addition of Bryostatin-1 restored the loss of LTB₄ induced neutrophil migration, while pretreatment with GO-6976 (PKCα and β inhibitor) did not. In addition using PKCδ and ε specific small interfering RNA, we were able to show that PKCδ, but not ε was at least mostly responsible for the loss of neutrophil migration in response to LTB₄. Taken together, these observations suggest that activation of endothelial PKCδ could be therapeutic in the treatment of various inflammatory disorders characterized by enhanced neutrophil infiltration.

This invention relates to pharmaceutical compositions, particularly pharmaceutical compositions comprising bryostatin-1 and substituted derivatives of bryostatin-1, thereof as pharmaceuticals for inhibition of inflammation, and for use in combating arteriosclerosis, diseases of the cardiovascular system, of the central nervous system and prior to/following organ transplantation, ischemia. The invention relates to methods for treating leukocyte dependent injury in chronic inflammatory diseases, and injury from transplantation mediated organ stress. The method involves injecting bryostatin-1 into patients with the inflammatory condition, treating the skin with bryostatin-1, or perfusing organs with bryostatin-1 prior to transplantation/cold storage. Activation of protein kinase Cd (PKCd) results in a near complete blockade of leukocyte infiltration which is the result of stabilization of the microvascular (endothelial) barrier.
