lnflammatory reactions are generated in response to extemal and intemal stimuli, such as infection, trauma, clinical insult or dysregulation of the umnune system. The int1ammatory responses may bc antigen-specific or non-specific, local or systemic, chronic or rapid and severe, characterized by a massive release of mediators, often lethal. The aim of this book is to review selectcd aspects associated with the mechanism of the pathology of int1ammatory processes of ditlerent origin and to evaluate therapeutic strategies aimed at combating various inflamma- tory diseases. The introductory article describcs the inmlllnological status of patients with severe sepsis, with particular attention paid to the roJe of circulating neutrophils. Intcgrin activation and chemokine receptor expression and the roles of IL-15, prostaglandins and leukotriens in inflmmnation and immunity are the subjects of next articles. Subsequent reviews are focused on allergic diseases involving mast cells and Th2 type cytokines, in particular the mech- anisms of atopic dennatitis and signaling hy IL-13. The intlmmnatory responscs elicited by Mycobacterium tuberculosis and Mvcobacferium nviwn are also analyzed with special interest paid to the mechanisms which allow the bacteria to escape the host' s immune reactions. The thcrapeutic potential of IL- I 0 in infection and inflammation and thc possible factors contributing to the devclopment of idiopathic pulmonary fibrosis are rcvicwed in the next articles. The final report demonstrates the advantages of bacteriophage ther- apy in thc context of the aggravating problem of hactcrial resistance to antibi- otics.

The immune system has evolved mechanisms enabli ng it to discriminate between self and non-self constituents. A normally functioning organism is naturally unresponsive to self antigens originating from clonal deletion, aner- gy, or an active suppression of self-reactive T cells. The wide spectrum of autoimmune responses may be divided into systemic and organ-specific dis- eases and encompasses the actions of autoantibodies, autoantigeu-autoanti- body complexes, and sensitized T lymphocytes. The aim of this book is to review the current understandin g, concepts and hypotheses regarding the pathogenesis and therapeutic approaches in autoim- mune disorders. The first six articles are generally concerned with the mech- anisms operating in autoimmune phenomena, whereas the subsequent reviews discuss particular phenomena in representative autoimmune dis- eases. The introductory article underlines the significance of the interactions between antigen-specific T cells and other elements ot the immune system and proposes that not suppression, but rather activation of the immune sys- tem, leading to a redirection of the immune response, would be therapeuti- cally beneficial. The next articles present the importance of costim ulatory signals in determining various types of immune responses, including autoim- munity, and the role of regulatory T cells. Further, an interesting phenome- non of epitope spreading as a mechanism for the progression of autoimmune diseases is presented.
