Abstract: The present invention relates to Death Receptor-6 (DR6) proteins which are members of the tumor necrosis factor (TNF) receptor family, and have now been shown to be important for regulating apoptosis in cells of the nervous system. In addition, it has been discovered that p75 is a ligand for DR6. As a result, this invention relates to methods for inhibiting the interaction of DR6 and p75 using DR6 and/or p75 antagonists. In addition, the methods described herein include methods of promoting survival of cells of the nervous system using DR6 antagonists, optionally in combination with p75 antagonists, and methods of treating neurodegenerative conditions by the administration of a DR6 antagonists, optionally in combination with a p75 antagonist.

Abstract: BAFF plays a central role in acquired immunity. The disclosure identifies BAFF-responsive genes that are substantially upregulated by administration of BAFF and substantially downregulated by treatment with a BAFF antagonist. Specific genes are: NF-?B2, CD23, H2-M? (the beta chain of H2-DM), Fig-1, and OBF-1. The disclosure provides methods and compositions for: monitoring the activity of a BAFF antagonist in a mammal; monitoring BAFF activity in a mammal; identifying a mammal to be treated with a BAFF antagonist; and related uses. Such methods include detecting one or more molecules selected from the group consisting of Fig-1 molecule, OBF-1 molecule, and H2-M? molecule in a biological sample of the mammal, and optionally further detecting NF-?B2 molecule and/or CD23 molecule in the biological sample.

Abstract: The compositions and methods of the present invention are based, in part, on our discovery that an effector function mediated by an Fc-containing polypeptide can be altered by modifying one or more amino acid residues within the polypeptide (by, for example, electrostatic optimization). The polypeptides that can be generated according to the methods of the invention are highly variable, and they can include antibodies and fusion proteins that contain an Fc region or a biologically active portion thereof.

Abstract: Provided herein is a method of monitoring the change of the alpha-4 integrin activities in an individual by correlating with the soluble vascular cell adhesion molecule (sVCAM) and/or soluble mucosal addressin cell adhesion molecule (sMAd-CAM) levels. Particularly, this method can be used, for example, to evaluate the pharmacokinetics and pharmacodynamics (PK/PD) of an alpha-4 integrin inhibitor used to treat a disease associated with pathological or chronic inflammation.
Abstract: Endogenous Sp35 is a negative regulator for neuronal survival, axon regeneration, oligodendrocyte differentiation and myelination (Negative Regulator).

Abstract: Disclosed is a method for enhancing or increasing the concentration of biological product in a final mixture, wherein said biological product has one or more selected characteristics, wherein said method comprises: (a) allowing an initial mixture of biological products with and without said selected characteristics to contact a chromatography medium wherein the quantity of biological products in said initial mixture exceeds the binding capacity or the dynamic binding capacity of said chromatography medium; (b) allowing biological product not having said one or more selected characteristics to be separated by said chromatography medium; and (c) recovering a final mixture of biological products from said chromatography medium wherein said final mixture comprises an enhanced or increased concentration of biological product with one or more selected characteristics, compared to the concentration of biological product in said initial mixture.
Abstract: The instant invention describes methods of separating or preferentially synthesizing dimers which are linked via at least one interchain disulfide linkage from dimers which are not linked via at least one interchain disulfide linkage from a mixture comprising the two types of polypeptide dimers. These forms can be separated from each other using hydrophobic interaction chromatography. In addition, the invention pertains to connecting peptides that result in the preferential biosynthesis of dimers that are linked via at least one interchain disulfide linkage or that are not linked via at least one interchain disulfide linkage. The invention also pertains to compositions in which a majority of the dimers are linked via at least one interchain disulfide linkage or are not linked via at least one interchain disulfide linkage. The invention still further pertains to novel binding molecules, e.g., comprising connecting peptides of the invention.

Abstract: The present invention provides automated systems and methods for monitoring column performance in process chromatography, and applications thereof. In an embodiment, column performance is monitored by generating a plurality of process values such as, for example, conductivity values or pH values with a detector during a chromatography step transition between a first mobile phase liquid and a second mobile phase liquid. The process values are transformed to form transformed process values in which noise present in the process values is suppressed. Column performance parameters are calculated based on the transformed process values and displayed during movement of the second mobile phase liquid through the chromatography column.
