SAN DIEGO, Feb. 27, 2019 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel immunological pathways, today announced a poster presentation at the Keystone Symposia 2019 Conference in Santa Fe, New Mexico from February 24-28, 2019.
“We are pleased to present these important preclinical findings at Keystone Symposia 2019, the first evidence of ATYR1923’s ability to bind to NRP-2 and down-regulate myeloid cells, specifically neutrophils,” said Dr. Sanjay Shukla, President and Chief Executive Officer of aTyr. “With ATYR1923 currently being evaluated in a Phase 1b/2a clinical study in patients suffering from pulmonary sarcoidosis, these findings help support our belief in the mechanism of action of ATYR1923 to suppress immune engagement in this and other serious and potentially debilitating interstitial lung diseases.”
Wednesday, February 27, 2019 from 1:30-3:00pm (MST)
Title: “ ATYR1923 Reduces Neutrophil Infiltration in an Acute Lipopolysaccharide (LPS) Lung Injury Model”
Presenter: Suzanne Paz, Ph.D., aTyr Pharma, Inc.
This poster describes a preclinical study to determine if aTyr Pharma’s lead clinical candidate, ATYR1923, can influence myeloid cell migration. ATYR1923 was administered intravenously to C57BL/6 mice 24 hours prior to LPS challenge by airway administration to generate acute lung inflammation.
Multi-color flow cytometry was used for immunophenotyping analysis and detection of NRP-2 levels on surfaces of various immune cell populations. In vitro, mouse bone-marrow derived macrophages (BMDM), human THP-1 monocytic cells, and primary human dendritic cells (DCs) were used to confirm induction of NRP-2 cell surface expression following activation.
