Disclosed herein are compositions and methods for regulating redox status and/or reducing oxidative stress in a subject, the methods and compositions comprising TLR agonists comprising bacterial lysates and/or lysate fractions. Also disclosed are compositions and methods comprising bacterial lysates and/or lysate fractions formulated or administered in combination with one or more other therapeutic or pharmaceutical agents.

Also disclosed are compositions and methods comprising bacterial lysates and/or lysate fractions formulated or administered in combination with one or more other therapeutic or pharmaceutical agents.

The disclosure provides oral compositions and methods of using such compositions in treating subjects infected with one or more hepatic disorders. The compositions include lysates or cell wall extracts of one or more gram positive bacteria, exhibit particular activity against hepatitis C virus (HCV), and may be useful in treating those infected with HCV as well as other hepatic diseases or disorders. Also described are methods of treating a hepatic disease or disorder by administering a therapeutically effective amount of at least one therapeutically active agent capable of upregulating or downregulating the Complement system pathway, wherein the therapeutically active agent enhances the formation of one or more convertase enzymes.

The invention relates to polypeptides, and in particular to polypeptides that are capable of inhibiting the activity or activation of the complement system. It also relates to nucleic acids that encode the polypeptides and to uses of the polypeptides.

The complement system helps or complements the ability of antibodies and phagocytic cells to clear pathogens from an organism. It forms part of the innate immune system. Down-regulation of complement activation has been demonstrated to be effective in treating several disease indications in animal models and in ex vivo studies. The present invention provides novel polypeptides that can be used for the treatment of diseases or disorders that relate to inappropriate activation of one or more of the complement pathways.

In one aspect, affinity tags for recombinant protein purification are described herein which, in some embodiments, can mitigate or overcome disadvantages of prior affinity tag systems. In some embodiments, for example, affinity tags described herein permit efficient elution of desired recombinant proteins with simplified solution systems, such as alkali metal salt solutions. An affinity tag described herein comprises an amino acid sequence including a repeating amino acid unit of BXXXBXX, wherein B is an amino acid selected from the group consisting of histidine, lysine and arginine and X is an amino acid selected from the group consisting of amino acids other than histidine, lysine and arginine.
