Jan 2021
Provided herein are fusion protein constructs that can bind a complement-associated antigen, comprising a targeting moiety and a complement modulator protein, or a fragment thereof or a variant thereof. The targeting moiety is an antibody or an antigen binding fragment thereof, in some examples. Further provided are methods of using the fusion protein constructs, for example, in treating complement mediation conditions.

Marker Sequences for Diagnosing and Stratifying Systemic Sclerosis Patients

Budde, Petra
Jan 2021
The present invention relates to methods for identifying markers for systemic sclerosis (also scleroderma; SSc) and to the markers identified with the aid of this method, which can differentiate between SSc and other autoimmune diseases on the one hand and between different SSc subgroups on the other hand. The invention also relates to panels, diagnostic devices and test kits which comprise these markers, and to the use and application thereof, for example for the diagnosis, prognosis and therapy control of SSc. The invention also relates to methods for screening and for validating active substances for use in SSc.

Genomics-Driven Immunoproteomics: An Integrative Platform to Uncover Important Biomarkers for Human Diseases

Genomics-driven immunoproteomics (GDI) is a platform that helps identify antigenic protein targets of mutations and other deoxyribonucleic acid (DNA) variations that are commonly associated with pathological states. This platform utilizes data generated from deep sequencing of exomic DNA or ribonucleic acid (RNA) as input to synthesize mutant peptides into microarrays, which then can be used to detect antigenic proteins that invoke immune response in patients. The technology has been used to detect antigenic targets of multiple sclerosis, an autoimmune disease [1], and cancer to identify mutant proteins that invoke immune response in breast cancer patients [2]. This technology has many potential applications to select genomic changes that are specifically recognized by the immune system in a rapid and efficient manner.

Bacterial inhibitors

Xie, Hua
Jul 2019
Peptides related to certain portions of the arginine deiminase enzyme from the bacterium Streptococcus cristatus are provided that disrupt the formation and composition of biofilms containing the oral pathogen Porphyromonas gingivalis, and also modulate the virulence of P. gingivalis. Pharmaceutical compositions containing such peptides and method of using the same are disclosed.

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.
