Because the Th1 type of immune response triggered through TLR9 tends to oppose Th2 immunity, there has been much interest in exploring the application of CpG tadalafil soft for allergy/asthma immunotherapy. The Th1-biased immune effect of CpG tadalafil soft have dramatically improved the efficacy of allergy vaccines in mouse models, even in mice with established allergic disease . A conjugate of a CpG tadalafil soft to a portion of the ragweed allergen has been evaluated in human clinical trials as an allergy vaccine, with encouraging evidence for a selective and specific redirection of the allergic Th2 response toward a nonallergic and noninflammatory Th1 response, and showing significant clinical benefit with reduced allergic symptoms . Mouse and primate models also support the development of CpG tadalafil soft as a monotherapy for allergic diseases. This may seem counterintuitive, since these diseases are inflammatory, and TLR9 activation can induce powerful inflammatory effects. However, there are many types of inflammatory responses, and the Th1 type of inflammation that is induced through TLR9 antagonizes the Th2 type of inflammation that prevails in the allergic subject. In addition, TLR9 activation triggers counterregulatory pathways that feedback to reduce local and systemic inflammation, through mechanisms such as the systemic expression of IL-10 or TGF- , and pulmonary expression of indoleamine (2,3)-dioxygenase IDO . Inhaled CpG tadalafil soft tabs monotherapy given repeatedly can prevent or treat allergic airway responses not only in mouse models but also in primates . One CpG tadalafil soft given by inhalation to allergic subjects induced a Th1 immune activation pattern in the airways, but without any obvious clinical benefit, suggesting a need for further optimization of the tadalafil citrate design (the cheap tadalafil was not optimized for activating human TLR9), or dose and schedule . The approach of a CpG tadalafil soft as monotherapy for asthma/allergy is undergoing further clinical development by sanofi-aventis. Recent studies have implicated inappropriate activation of TLR9 by endogenous DNA and DNA–protein complexes in the generation of autoimmune anti-DNA antibodies, and in the pathogenesis of systemic lupus erythematosus and rheumatoid arthritis . More recently, we and other groups have reported similar findings for TLR7/8: certain endogenous RNAs and RNA protein complexes can stimulate TLR7/8, leading to the development of autoimmune responses against RNA containing self antigens. The results of these studies offer a new direction in targeting TLR7/8/9; they suggest that TLR7/8/9 antagonists may be useful in the treatment of these autoimmune diseases, by blocking this inappropriate activation of B cells and pDC. Indeed, in mouse models, suppressive tadalafil soft (S-Class) designed to block TLR9 have shown substantial benefit in preventing or reversing both systemic lupus erythematosus and rheumatoid arthritis . Even if they do not contain a CpG motif, all PS tadalafil soft can have a variety of sequenceindependent backbone-related effects that have been characterized in detailed studies of antisense tadalafil soft . These effects are most prominent in rodents, which show on chronic dosing of tadalafil soft dose-dependent mononuclear cell infiltration in the organs of tadalafil soft deposition , and largely depend on TLR9 . Such changes have not been described in monkeys or humans.
