Islet Encapsulation: New Developments for the Treatment of Type 1 Diabetes

Sandrine Gerber, Qixing Zhang, Yi Wang, Léo Bühler

Islet transplantation is a promising approach for the treatment of type 1 diabetes (T1D). Currently, clinical islet transplantation is limited by allo - and autoimmunity that may cause partial or complete loss of islet function within a short period of tim ...

Biology and therapeutic targeting of tumour-associated macrophages

Michele De Palma, Tim Beltraminelli

Macrophages sustain tumour progression by facilitating angiogenesis, promoting immunosuppression, and enhancing cancer cell invasion and metastasis. They also modulate tumour response to anti-cancer therapy in pre-clinical models. This knowledge has motiva ...

Inflammation clues in STING protein structure

Andrea Ablasser

The STING protein aids intracellular defences by triggering inflammation. Studies that uncover how STING is activated might lead to strategies for targeting this protein in the treatment of cancer or autoimmune diseases. ...

Innovative Tools and in vivo Methods for Tuberculosis Drug Discovery and Development

Raphael Christopher Sommer

Worldwide, tuberculosis (TB) is the leading cause of death due to a single infectious agent, claiming 1.6 million human lives and causing >10 million new cases in 2017 alone, mostly in low-income regions. The intracellular pathogen Mycobacterium tuberculos ...

More Medicines for Tuberculosis: Fuelling Drug Discovery against Mycobacterium tuberculosis

Shi-Yan Caroline Foo

Tuberculosis (TB), whose etiological agent is Mycobacterium tuberculosis (M. tuberculosis), has plagued humanity since antiquity. Even with chemotherapy available today, TB is the leading cause of death due to an infectious disease. Modern day factors, suc ...

Fluorescent Benzothiazinone Analogues Efficiently and Selectively Label Dpre1 in Mycobacteria and Actinobacteria

Paul Joseph Dyson, Stewart Cole, John McKinney, Neeraj Dhar, Thierry Laroche, Jérémie Piton, Joao Pedro De Almeida Neres, Raphael Christopher Sommer, Raju Mukherjee

Benzothiazinones (BTZ) are highly potent bactericidal inhibitors of mycobacteria and the lead compound, BTZ043, and the optimized drug candidate, PBTZ169, have potential for the treatment of tuberculosis. Here, we exploited the tractability of the BTZ scaf ...

Bioengineering strategies for inducing tolerance in autoimmune diabetes

Jeffrey Alan Hubbell, Steinunn Baekkeskov Hanahan, Edward Allen Phelps

Type 1 diabetes is an autoimmune disease marked by the destruction of insulin-producing beta cells in the pancreatic islets. Strategies to delay onset or prevent the autoimmune recognition of beta cell antigens or T cell-mediated killing of beta cells have ...

Primary human and rat beta cells release the intracellular autoantigens GAD65, IA-2 and proinsulin in exosomes together with cytokine-induced enhancers of immunity

Michele De Palma, Jeffrey Alan Hubbell, Davide Demurtas, Romain Hamelin, Steinunn Baekkeskov Hanahan, Chiara Cianciaruso, Melody Swartz, Sachiko Hirosue, Miriella Carmela Pasquier, Edward Allen Phelps

The target autoantigens in several organ-specific autoimmune diseases, including type 1 diabetes (T1D), are intracellular membrane proteins, whose initial encounter with the immune system is poorly understood. Here we propose a new model for how these prot ...

Investigating the Biological Mechanisms underlying the Initiation of Autoimmunity against Beta Cell Antigens in Type 1 Diabetes

Chiara Cianciaruso

Type 1 diabetes (T1D) is an autoimmune disease characterized by circulating autoantibodies, lymphocytic infiltration of pancreatic islets of Langerhans, and cell-specific destruction of beta cells, leading to insulin deficiency and symptomatic hyperglycemi ...

Mechanisms of tolerance induction by erythrocyte-targeted antigens

Alizée Jéléna Grimm

Immune-mediated disorders such as autoimmune diseases, graft-versus-host disease or allergies, are a major contemporary burden. Despite significant advances in the field of immunological tolerance, immunosuppressive drugs are still the current hallmark for ...

Who will develop new antibacterial agents?

Stewart Cole

The golden age of antimicrobial drug development is a distant memory, and the likelihood of there being another seems slim. In part, this is because the pharmaceutical industry, which has now adopted an unsustainable business model, abandoned the anti-infe ...

Engineering antigens for in situ erythrocyte binding induces T-cell deletion

Jeffrey Alan Hubbell, Stephane Kontos, Iraklis Kourtis, Karen Dane

Antigens derived from apoptotic cell debris can drive clonal T-cell deletion or anergy, and antigens chemically coupled ex vivo to apoptotic cell surfaces have been shown correspondingly to induce tolerance on infusion. Reasoning that a large number of ery ...

Cre-mediated cell ablation contests mast cell contribution in models of antibody- and T cell-mediated autoimmunity

Nicola Harris

Immunological functions of mast cells remain poorly understood. Studies in Kit mutant mice suggest key roles for mast cells in certain antibody- and T cell-mediated autoimmune diseases. However, Kit mutations affect multiple cell types of both immune and n ...
