Abstract: The present disclosure provides binding proteins (e.g., antibodies or antigen binding fragments thereof) that specifically bind to Klebsiella pneumoniae O1 and induce opsonophagocytic killing of Klebsiella (e.g., Klebsiella pneumoniae). The present disclosure also provides methods of reducing Klebsiella (e.g., Klebsiella pneumoniae) or treating or preventing Klebsiella (e.g., Klebsiella pneumoniae) infection in a subject comprising administering the Klebsiella pneumoniae O1 binding proteins, (e.g., antibodies or antigen-binding fragments thereof) to the subject.
Abstract: This disclosure provides LOX1 (LOX1) binding proteins such as anti-LOX1 antibodies, and compositions and methods for making these binding proteins. In certain aspects the LOX1-binding proteins provided herein, inhibit, or antagonize LOX1 activity. In addition, the disclosure provides compositions and methods for diagnosing and treating conditions associated with atherosclerosis, thrombosis, coronary artery disease (CAD), ischemia (e.g., myocardial ischemia), infarction (e.g., myocardial infarction), acute coronary syndrome (ACS), stroke, reperfusion injury, restenosis, peripheral vascular disease, hypertension, heart failure, inflammation (e.g., chronic inflammation), angiogenesis, preeclampsia, cancer and other LOX1-mediated diseases and conditions.

Abstract: This disclosure provides compositions and methods for controlling pain. In particular the disclosure provides a method for controlling pain comprising co-administration of an NGF antagonist and a TNF? antagonist. The NGF antagonist and the TNF? antagonist can be separate molecules or part of a multifunctional polypeptide, e.g., a multispecific binding molecule that comprises an NGF antagonist domain and a TNF? antagonist domain. This disclosure also provides multifunctional polypeptides, e.g., multispecific binding molecules, comprising an NGF antagonist domain, and a TNF? antagonist domain. The method provides improved pain control. Administration of an NGF antagonist and a TNF? antagonist as provided herein can control pain in the subject more effectively than an equivalent amount of the NGF antagonist or the TNF? antagonist administered alone.
