Anti-Trail Antibodies and Methods of Use

Boico, Olga; Tzaban, Salit; Oved, Kfir; Cohen-Dotan, Assaf; Eden, Eran
May 2019
An antibody comprising an antigen recognition domain that binds specifically the extracellular domain of TNF-related apoptosis-inducing ligand (TRAIL) between amino acids 95-155 and/or amino acids 190-210 is disclosed. Uses thereof are also disclosed.

ABSTRACT Revealing the molecular organization of anatomically precisely defined brain regions is necessary for the refined understanding of synaptic plasticity. Although, three-dimensional (3D) single-molecule localization microscopy can provide the required molecular resolution, single-molecule imaging more than a few micrometers deep into tissue remains challenging. To quantify presynaptic active zones (AZ) of entire, large, conditional detonator hippocampal mossy fiber (MF) boutons with diameters as large as 10 µm, we developed a method for aberration-free volumetric direct stochastic optical reconstruction microscopy ( d STORM). An optimized protocol for fast repeated axial scanning and efficient sequential labeling of the AZ scaffold Bassoon and membrane bound GFP with Alexa Fluor 647 enables 3D- d STORM imaging of 25 µm thick mouse brain sections and assignment of AZs to specific neuronal substructures. Quantitative data analysis revealed large differences in Bassoon cluster size and density for distinct hippocampal regions with largest clusters in MF boutons.

ANTIBODY TARGETING CELL SURFACE DEPOSITED COMPLEMENT PROTEIN C3d AND USE THEREOF

Wiestner, Adrian U.; Skarzynski, Martin W.; Lindorfer, Margaret A.; Taylor, Ronald P.; Rader, Christoph; Vire, Berengere
Feb 2019
An anti-C3d antibody or antibody fragment; method for use thereof to kill cancer cells; and related methods and compositions.

Methods of Selecting Binding Reagents

Mallick, Parag; Egertson, Jarrett
Feb 2019
Methods and systems are provided herein for selecting an affinity reagent which binds a desired peptide epitope in a plurality of sequence contexts. The method relies on obtaining a peptide library, each peptide having the sequence αΧβ, wherein X is the desired peptide epitope, wherein each of a and β comprise an amino acid, using the peptide library to select an affinity reagent.

High-Density Peptide Arrays for Malaria Vaccine Development

The development of an efficacious and practicable vaccine conferring sterile immunity towards a Plasmodium infection represents a not yet achieved goal. A crucial factor for the impact of a given anti-plasmodial subunit vaccine is the identification of the most potent parasitic components required to induce protection from both infection and disease. Here, we present a method based on a novel high-density peptide array technology that allows for a flexible readout of malaria antibodies. Peptide arrays applied as a screening method can be used to identify novel immunogenic antibody epitopes under a large number of potential antigens/peptides. Ultimately, discovered antigen candidates and/or epitope sequences can be translated into vaccine prototype design. The technology can be further utilized to unravel antibody-mediated immune responses (e.g., involved in the establishment of semi-immunity) and moreover to confirm vaccine potency during the process of clinical development by verifying the induced antibody responses following vaccination.
