As the world races to develop vaccines against SARS-CoV-2, Dai and Gao highlight which viral targets are best to include in a vaccine and how this impacts the induced immune response and, ultimately, the safety and efficacy of a vaccine.
In this Progress article, Wang and Colonna highlight a flurry of recent reports that have shaped our understanding of how environmental cues and clock genes regulate group 3 innate lymphoid cells. They consider the implications of these findings for intestinal immunity.
In this Progress article, Zeyu Chen and E. John Wherry summarize early reports of the T cell responses observed in patients with COVID-19, emphasizing how different immune response characteristics in different patients may reflect a spectrum of disease phenotypes.
This Progress article from Merad and Martin examines our current understanding of the excessive inflammatory responses seen in patients with severe COVID-19. The authors focus on the emerging pathological roles of monocytes and macrophages and discuss the inflammatory pathways that are currently being targeted in the clinic.
Freeman and colleagues draw our attention to the existence of different forms of PDL1 — cell bound and various extracellular forms. Recent studies show that PDL1 on exosomes can inhibit antitumour immune responses and may be a useful biomarker for the management of cancer immunotherapy.
