“Cytokine storm” describes an excessive cytokine/chemokine increase in the blood which is observed in some COVID-19 patients as a consequence of an overexuberant immune response. The authors asked whether a cytokine storm is associated with better or poorer anti-SARS-CoV-2 antibody production. They found that anti-SARS-CoV-2 IgG titers were significantly higher in severely ill patients than in moderately ill patients, but such a difference was not observed for IgM. High titers of early-stage IL-6, IL-8, and TNF-α (≤2 weeks after symptom onset) were positively correlated with high titers of late-stage IgG (≥5 weeks after symptom onset). Early responses resulting in elevated titers of cytokines such as IL-6 are thus associated with high titers of IgG antibodies against COVID-19.

Our knowledge of the negative consequences of the important differences of immune function seen in younger and older individuals is scarce, and mostly limited to humans, mice and to some extent monkeys and companion animals. However, comparative studies of the health impacts of immune ageing in other species, potentially including invertebrates, and in kingdoms other than animals, are scarcer still, but might shed light on some common features required for survival in a dangerous world. This Topical Collection accordingly aims to solicit papers on any aspect of immune ageing in species other than humans and mice. Reviews, original articles, commentaries, hypotheses and opinion pieces are all very welcome.
‘Immunosenescence’ describes the multifactorial changes in the immune system with advanced age. To increase our understanding of the conditions of immune function in aging, the focus of this special issue is to document biomarkers of age-related immune conditions. We seek articles which highlight validated biomarkers or approaches to quantify immune aging, clarify heterogeneity among changes that accrue in aging, identify mechanisms underlying the altered state, or highlight where interventions may serve to improve health. Articles may be commentaries or original research. Articles especially welcomed will address conceptual topics, detectable biomarkers, or clinical implications.
This topical collection will explore how complex neuroimmune interactions promote healthy and pathological ageing. We seek reviews, viewpoints, commentaries, or original research articles exploring the role of stress, mood disorders, and sensory systems during normal and premature immunosenescence. Over the last few decades, increasing evidence is implicating a role for the immune system in brain physiology and behaviour. Therefore, we also welcome articles discussing the role of immune cells and cytokines for the ageing brain, as well as the role of inflammation in neuromuscular disorders associated with senescence. In addition, we seek articles exploring the role of immunosenescence in age-related pathologies of the nervous system, including neurodegenerative and autoimmune disorders (e.g., AD, PD and MS), as well as the role of vascular disease in neurodegeneration. In the context of the COVID-19 pandemic, we also seek articles discussing post-infectious degeneration in older adults.
Seasonal influenza is a common respiratory infection that causes significant health burden worldwide, particularly in older adults. Studies of altered immune functions with aging in human and animal model systems have identified underlying mechanisms and offer potential therapeutic insights. Vaccination is an effective tool to reduce and even prevent severe infection and its complications. Recent improvements in vaccine design enhance vaccine efficacy for at-risk older adults. Understanding innate, humoral and cellular conditions of the host immune system that contribute to severe infection and to age-associated alterations in vaccine response represent important steps in reducing the disease burden of influenza for the growing older adult population.

The increasing realization that immune ageing and organismal ageing are intimately inter-related puts the immune system at centre-stage in our efforts to understand and manipulate the ageing process.
Immunity & Ageing provides a specific conduit for dissemination of new knowledge in this increasingly important arena. Published since 2004, the journal is a specialist open access journal dedicated to promulgating information on the impact of ageing on immune systems, the influence of aged immune systems on organismal well-being and longevity, age-associated diseases which have at least partly an immune etiology, and potential immune interventions to increase health span.
Immunity & Ageing welcomes submissions dealing with any aspect of ageing in human and model organisms that relates to immune function. Papers dealing with any aspect of ageing that does not include a substantial immunological element will not be considered.

Graham Pawelec is Professor of Experimental Immunology at the University of Tübingen, Germany, where he led the Tübingen Ageing and Tumour Immunology (TATI) group from 1999 to 2017. He is currently affiliated with the Health Sciences North Research Institute of Canada, Sudbury, ON, and is a Visiting Professor at Nottingham Trent University, King´s College London, and Manchester University, UK. His research interests remain centered on immunogerontology in the context of cancer immunology and immunotherapy, and vaccination.
Nan-ping Weng is tenured senior investigator, Chief of Lymphocyte Differentiation Section, Laboratory of Molecular Biology and Immunology at the National Insitute on Aging (NIA), NIH. He joined the Laboratory of Immunology at the NIA as a tenure-track investigator in 1997 and has been tenured senior investigator since 2006. His laboratory focuses on the understanding of molecular and cellular mechanisms of T cell differentiation and age-associated decline of T cell functions.
