Abstract: The invention relates to methods and products for the identification of a clinically significant immune response in subjects treated with a therapeutic protein. A first aspect of the invention relates to methods and compositions for identifying a clinically significant immune response in patients treated with therapeutic amounts of VLA4 binding antibody (e.g., natalizumab). A second aspect of the invention concerns the chronological details of sample collection for determining the titer of antibodies against the therapeutic protein, e.g. the collection of at least two samples at two different time points. A third aspect of the invention relates to the selection of the critical threshold level, which corresponds to the antibody titer of untreated patients increased by the double of the standard deviation of this control antibody titer.

Abstract: Methods and compositions for determining whether a subject is at risk for PML, including subjects being treated with immunosuppressants, by determining whether the subject harbors a JCV variant with reduced binding for sialic acid relative to a normal JCV, are presented. Furthermore, combinations of JCV-VP1 sequence variations that are associated with PML and that can be used as a basis of an assay for identifying subjects susceptible to PML, subjects with PML (e.g., early stage PML), or subjects at risk of developing PML in response to an immunosuppressive treatment are provided.

Abstract: The invention is based, at least in part, on the finding that a dimeric version of a BBB-transmigrating antibody (e.g., the TMEM30A (CDC-50A) binding antibody, FC5) was found to greatly enhance transport across the BBB as compared to monovalent FC5 VHH. The invention provides, inter alia, molecules that increase transport of pharmacologically active agents across the blood brain barrier, methods for increasing transport across the blood brain barrier, and methods of treatment of disorders or diseases having a neurological component.

Abstract: Systems, devices, and methods for the delivery of gas bubbles to liquids are generally described. The devices can include a primary conduit (102) comprising a plurality of openings (104) fluidically connecting an internal flow pathway (106) of the primary conduit to an environment outside the primary conduit. The devices may also include, in some instances, a secondary conduit (114) located at least partially within the primary conduit, the secondary conduit configured to redistribute the pressure of the gas delivered to the openings of the primary conduit, and comprising a plurality of openings (116) fluidically connecting an internal flow pathway (118) of the secondary conduit to a portion of the internal flow pathway (106) of the primary conduit outside the secondary conduit. Certain of the gas delivery systems and methods described herein are capable of delivering gas at relatively uniform linear flow velocities across multiple gas outlet openings.
