Activation of TGFβ signalling in invasive margins of metastatic tumours can contribute to T cell exclusion and reduced immune checkpoint therapy response.
This Review describes recent advances in our understanding of the ontogeny, development and function of brain-resident macrophages and microglia, including their normal functions during brain development and homeostasis and how disturbance of these functions may precipitate neurodegenerative and neuropsychiatric diseases.
Peptidoglycan is an important structural component of bacterial cell walls, and mammalian cells express a number of distinct pattern-recognition receptors that detect peptidoglycan fragments. Here, the authors discuss new insights into the role of peptidoglycan recognition in inflammation, metabolism and disease.
The development of multiphoton intravital microscopy has enabled detailed studies of humoral responses within lymphoid tissues. Here, Kuka and Iannacone cover recent studies of the viral subversion of B cell responses and discuss how these findings relate to our understanding of B cell activation within secondary lymphoid organs.
Although systemic infection is a hallmark of malaria disease, less is known regarding how parasitized erythrocytes interact locally with host tissues. In this Review, the authors discuss how infected erythrocytes reach different tissue environments and cause specific pathological consequences in malaria.
In this Opinion article, the authors consider how poverty and diet can shape the microbiota and immune health. They highlight how this contributes to the greater levels of chronic disease that are experienced by low-income individuals in high-income societies.
