Abstract

Individuals with potential exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) do not necessarily develop PCR or antibody positivity, suggesting that some individuals may clear subclinical infection before seroconversion. T cells can contribute to the rapid clearance of SARS-CoV-2 and other coronavirus infections1–3. Here we hypothesize that pre-existing memory T cell responses, with cross-protective potential against SARS-CoV-2 (refs. 4–11), would expand in vivo to support rapid viral control, aborting infection. We measured SARS-CoV-2-reactive T cells, including those against the early transcribed replication–transcription complex (RTC)12,13, in intensively monitored healthcare workers (HCWs) who tested repeatedly negative according to PCR, antibody binding and neutralization assays (seronegative HCWs (SN-HCWs)). SN-HCWs had stronger, more multispecific memory T cells compared with a cohort of unexposed individuals from before the pandemic (prepandemic cohort), and these cells were more frequently directed against the RTC than the structural-protein-dominated responses observed after detectable infection (matched concurrent cohort). SN-HCWs with the strongest RTC-specific T cells had an increase in IFI27, a robust early innate signature of SARS-CoV-2 (ref. 14), suggesting abortive infection. RNA polymerase within RTC was the largest region of high sequence conservation across human seasonal coronaviruses (HCoV) and SARS-CoV-2 clades. RNA polymerase was preferentially targeted (among the regions tested) by T cells from prepandemic cohorts and SN-HCWs. RTC-epitope-specific T cells that cross-recognized HCoV variants were identified in SN-HCWs. Enriched pre-existing RNA-polymerase-specific T cells expanded in vivo to preferentially accumulate in the memory response after putative abortive compared to overt SARS-CoV-2 infection. Our data highlight RTC-specific T cells as targets for vaccines against endemic and emerging Coronaviridae.

Abstract

In the USA, Black men are approximately twice as likely to be diagnosed with and to die of prostate cancer than white men. In the UK, despite Black men having vastly different ancestral contexts and health-care systems from Black men in the USA, the lifetime risk of being diagnosed with prostate cancer is two-to-three times higher among Black British men than among white British men and Black British men are twice as likely to die of prostate cancer as white British men. Examination of racial disparities in prostate cancer in the USA and UK highlights systemic, socio-economic and sociocultural factors that might contribute to these differences. Variation by ancestry could affect incidence and tumour genomics. Disparities in incidence might also be affected by screening guidelines and access to and uptake of screening. Disparities in treatment access, continuity of care and outcomes could contribute to survival differences. In both localized and metastatic settings, equal access could diminish the observed disparities in both the USA and the UK. An understanding of behavioural medicine, especially an appreciation of cultural beliefs about illness and treatment, could inform and improve the ways in which health systems can engage with and deliver care to patients in minoritized groups affected by prostate cancer. Methods of promoting equity include targeting systemic barriers including systemic racism, proportional recruitment of patients into clinical trials, diversifying the health-care workforce and facilitating care informed by cultural humility. Actively engaging patients and communities in research and intervention might enable the translation of research into increasingly equitable care for patients with prostate cancer in the UK, the USA and globally., (© 2024.
