摘要:
The present invention relates to a method of preventing or treating a disease caused by bacterial infection by administering an effective amount of a modulator of bacterial adenylyl cyclase. The invention also provides pharmaceutical compositions useful for preventing or treating a disease, with the compositions containing a therapeutically effective amount of a modulator of bacterial adenylyl cyclase. The invention also provides screening methods for identifying selective modulators of bacterial adenylyl cyclase that do not substantially modulate adenylyl cyclase of the subject. The invention also provides methods for culturing bacterial pathogens and methods for inducing the pathogenic state in vitro.
摘要:
A pharmaceutical composition which comprises the c-kit ligand (KL) purified by applicants or produced by applicants' recombinant methods in combination with other hematopoietic factors and a pharmaceutically acceptable carrier is provided as well as methods of treating patients which comprise administering to the patient the pharmaceutical composition of this invention. This invention provides combination therapies using c-kit ligand (KL) and a purified c-kit ligand (KL) polypeptide, or a soluble fragment thereof and other hematopoietic factors. It also provides methods and compositions for ex-vivo use of KL alone or in combination therapy. A mutated KL antagonist is also described. Such an antagonist may also be a small molecule. Antisense nucleic acids to KL as therapeutics are also described. Lastly, compositions and methods are described that take advantage of the role of KL in germ cells, mast cells and melanocytes.

Soluble adenylyl cyclase (sAC) is implicated in proliferation of keratinocytes. Inhibitors of sAC are useful for the treatment and/or prevention of psoriasis and other hyperproliferative skin disorders. Assays to identify such compounds are also described.
摘要:
The invention provides a method for diagnosing a melanocytic proliferation in a subject comprising staining a sample of lesional melanocytes with an antibody against soluble adenylyl cyclase (sAC) and interpreting the sAC staining pattern, which is associated with a diagnosis of a melanocytic proliferation. The sAC staining pattern, which is complex, is discriminatory and distinctive according to the nature of the melanocytic proliferation. The sAC staining pattern comprises one or more of dot-like Golgi staining, broad granular Golgi staining, diffuse cytoplasmic staining, nucleolar staining, incomplete granular nuclear staining, and pan-nuclear staining. The method of the invention is particularly useful in confirming or disaffirming a diagnosis reached through conventional histologic examination of a sample. Additionally, the invention provides a kit for use in interpreting melanocytic proliferations.
