Clinical Grade Treg: GMP Isolation, Improvement of Purity by CD127pos Depletion, Treg Expansion, and Treg Cryopreservation
BACKGROUND Treg based immunotherapy is of great interest to facilitate tolerance in autoimmunity and transplantation. For clinical trials, it is essential to have a clinical grade Treg isolation protocol in accordance with Good Manufacturing Practice (GMP) guidelines. To obtain sufficient Treg for immunotherapy, subsequent ex vivo expansion might be needed. METHODOLOGY/PRINCIPAL FINDINGS Treg...
متن کاملGP96: safeguarding Treg
FOXP3 positive regulatory T cells (Tregs) are key players in maintaining peripheral immune tolerance. Multiple molecules and signaling pathways are involved in regulating Treg function. Understanding these mechanisms is vital to designing Treg-targeted immunotherapeutic strategies for cancer and other diseases. A recent study uncovered that endoplasmic reticulum resident chaperone, gp96, is ess...
متن کاملUV-induced Treg cells
Dendritic cells (DCs) are the master regulators of T cell recirculation, according to a study by Mora et al. on page 303. Memory T cells—thought to be programmed to return to the location in which they first encountered antigen—can be rerouted by an encounter with a DC from another location. Previous studies have shown that memory T cells express a characteristic array of adhesion molecules and...
متن کاملGATA3, HDAC6, and BCL6 Regulate FOXP3+ Treg Plasticity and Determine Treg Conversion into Either Novel Antigen-Presenting Cell-Like Treg or Th1-Treg
We conducted an experimental database analysis to determine the expression of 61 CD4+ Th subset regulators in human and murine tissues, cells, and in T-regulatory cells (Treg) in physiological and pathological conditions. We made the following significant findings: (1) adipose tissues of diabetic patients with insulin resistance upregulated various Th effector subset regulators; (2) in skin bio...
متن کاملSerum amyloid A overrides Treg anergy via monocyte-dependent and Treg-intrinsic, SOCS3-associated pathways.
The acute phase protein serum amyloid A (SAA) has been well characterized as an indicator of inflammation. Nevertheless, its functions in pro versus anti-inflammatory processes remain obscure. Here we provide unexpected evidences that SAA induces the proliferation of the tolerogenic subset of regulatory T cells (T(reg)). Intriguingly, SAA reverses T(reg) anergy via its interaction with monocyte...
