- Description:
- Mycobacterium tuberculosis (Mtb) infection elicits both protein and lipid antigen-specific T cell responses. However, the incorporation of lipid antigens into subunit vaccine strategies and formulations has been under-explored, and the properties of vaccine-induced Mtb lipid-specific memory T cells have remained elusive. Mycolic acid (MA), a major lipid component of the...

- Description:
- Stimulation of the cGAS-STING (cycle GMP-AMP synthase-Stimulator of Interferon Genes) pathway increases T cell activation and tracking into the tumor and reverses the immunosuppressive phenotype of myeloid cells. Direct targeting of the STING receptor using synthetic cyclic dinucleotide (CDN) ligands represents an attractive immunotherapeutic strategy for the treatment of lymphocyte-depleted...

- The airway epithelial cells (AECs) lining the conducting passageways of the lung secrete a variety of immunomodulatory factors. One interesting pair of molecules produces by AECs is IL-6 and prostaglandin E2 (PGE2). PGE2 limits lung inflammation and promotes bronchodilation. By contrast, IL-6 drives intense airway inflammation, remodeling, and fibrosis. The...

- Regulatory T (Treg) cells are required to control immune responses and maintain homeostasis, but are a significant barrier to antitumor immunity. Conversely, Treg instability, characterized by loss of the master transcription factor Foxp3 and acquisition of proinflammatory properties, can promote autoimmunity and/or facilitate more effective tumor immunity. A comprehensive understanding...
