The present invention provides for engineered molecular opsonins that may be used to bind biological pathogens or identify subclasses or specific pathogen species for use in devices and systems for treatment and diagnosis of patients with infectious diseases, blood-borne infections or sepsis. An aspect of the invention provides for mannose-binding lectin (MBL), which is an abundant natural serum protein that is part of the innate immune system. The ability of this protein lectin to bind to surface molecules on virtually all classes of biopathogens (viruses, bacteria, fungi, protozoans) make engineered forms of MBL extremely useful in diagnosing and treating infectious diseases and sepsis.

Provided are methods for evaluating the risk of an adverse clinical outcome in a subject, deciding whether to discharge or continue treating a subject (e.g., treatment on an inpatient basis), or to initiate or terminate treatment, selecting a subject for participation in a clinical study, and selecting a therapeutic treatment for a subject that include determining a level of ST2 in a biological sample from the subject and determining a level of galectin-3 in a biological sample from the subject. Kits are also provided that contain an antibody that specifically binds to ST2, an antibody that specifically binds to galectin-3, and instructions for using the kit to evaluate the risk of an adverse clinical outcome in a subject, to decide whether to discharge or continue treating a subject (e.g., treatment on an inpatient basis) or to initiate or terminate treatment, to select a subject for participation in a clinical study, and/or to select treatment for a subject.

The present invention relates to a lectin for use in the treatment, reduction in progression and curing of inflammation in a subject in need thereof. Pharmaceutical compositions comprising said lectin are also described. The lectin may comprise an amino acid sequence having sequence of SEQ ID NO: 1 or at least 60% homology to SEQ ID NO: 1.

In one aspect, the disclosure provides cross-linked materials that include multivalent lectins with at least two binding sites for glucose, wherein the lectins include at least one covalently linked affinity ligand which is capable of competing with glucose for binding with at least one of said binding sites; and conjugates that include two or more separate affinity ligands bound to a conjugate framework, wherein the two or more affinity ligands compete with glucose for binding with the lectins at said binding sites and wherein conjugates are cross-linked within the material as a result of non-covalent interactions between lectins and affinity ligands on different conjugates. These materials are designed to release amounts of conjugate in response to desired concentrations of glucose. Depending on the end application, in various embodiments, the conjugates may also include a drug and/or a detectable label.

The present invention relates to novel chimeric molecules of ficolin-associated polypeptides, such as fusion polypeptides for the use in the treatment of conditions associated with inflammation, apoptosis, autoimmunity, coagulation, thrombotic or coagulopathic related diseases. The present invention further relates to nucleic acid molecules encoding such fusion polypeptides, vectors and host cells used in the production of the fusion polypeptides.

Described herein are engineered microbe-targeting molecules, microbe-targeting articles, kits comprising the same, and uses thereof. Such microbe-targeting molecules, microbe-targeting articles, or the kits comprising the same can not only bind or capture of a microbe or microbial matter thereof, but they also have improved capability (e.g., enhanced sensitivity or signal intensity) of detecting a microbe or microbial matter. Thus, the microbe-targeting molecules, microbe-targeting articles, and/or the kit described herein can be used in various applications, e.g., but not limited to assays for detection of a microbe or microbial matter, diagnostic and/or therapeutic agents for diagnosis and/or treatment of an infection caused by microbes in a subject or any environmental surface, and/or devices for removal of a microbe or microbial matter from a fluid.

The present invention is directed respirable, dry powder particle formulations of lung surfactants that optionally comprise surfactant proteins and/or polypeptide and that are formulated for delivery to the pulmonary system via inhalation.

The present invention provides a CAR comprising a) an antigen binding domain specific for an antigen, b) a spacer, c) a transmembrane domain, and d) an intracellular signaling domain, wherein said spacer consists of 1, 2 or 3 C2-set Ig-like domain(s). Said C2-set Ig-like domain(s) may be selected from the group of C2-set Ig-like domains of the sialic acid binding Ig-like lectin (Siglec) family. A composition comprising a) an immune cell expressing said CAR, wherein said CAR is specific for a tag and b) a tagged polypeptide is also disclosed.

Disclosed herein are anti-Galectin-9 antibodies and methods of using in modulating (e.g., increasing) immune responses in a subject, either taken alone or in combination with an immune checkpoint inhibitor, such as a PD-1 inhibitor.
