Abstract: The present disclosure includes engineering methods and polypeptide libraries that are useful for introducing non-native binding sites into polypeptides. Also provided herein are polypeptides that bind to a CD98hc or transferrin receptor (TfR) protein, methods of generating such polypeptides, and methods of using the polypeptides to target a composition across the blood-brain barrier or to a CD98hc-expressing or TfR-expressing cell.

Abstract: Provided herein are proteins, which are capable of being transported across the blood-brain barrier (BBB) and comprise an alpha-L-iduronidase (IDUA) enzyme-Fc fusion polypeptide. Certain embodiments also provide methods of using such proteins to treat MPS I.

Abstract: In one aspect, antibodies that specifically bind to a human triggering receptor expressed on myeloid cells 2 (TREM2) protein are provided. In some embodiments, the antibody decreases levels of soluble TREM2 (sTREM2). In some embodiments, the antibody enhances TREM2 activity.

Abstract: Certain embodiments provide a method of providing added peripheral IDS activity to a subject with Hunter syndrome, comprising administering to the subject a therapeutically effective dose of a pharmaceutical composition comprising a protein comprising an IDS amino acid sequence and a TfR binding domain. The added peripheral IDS activity can be measured by comparing levels of keratan sulfate (KS) in the subject after administration of the pharmaceutical composition relative to a baseline level. Certain embodiments also provide methods of providing a clinical benefit to a subject with Hunter syndrome and improving treatment in a patient having non-neuronopathic Hunter syndrome, as well as methods and treatment regimens for resolving infusion related reactions (IRRs).

Abstract: The present disclosure relates generally to compounds and compositions, intermediates, processes for their preparation, and their use as kinase inhibitors.

Abstract: The present disclosure relates generally to methods and compositions for preventing or arresting cell death and/or inflammation.

Abstract: Methods and systems described herein may allow for the classification of microglial morphology at single cell resolution. Microglial cell states may be determined, and a biological sample from which the microglial cells are obtained may be classified based on the microglial cell states. Classifying microglial cells may involving segmenting microglia cells into soma and processes in immunofluorescence microscopy images. Additionally, a feature bank may be generated. Values of the features in the feature bank may be measured for an image. Cells may be clustered using the values of the features in the feature bank. The cells in a cluster may be compared to a reference cell with a known state and having known morphological properties. The cluster in the cell may then be assigned the same state as a reference cell. The amount of cells having the state may then be used to determine properties of the biological sample.
