Distinct B cell repertoires characterize patients with mild and severe COVID-19 [VDJ]

Project description:Protective immunity against COVID-19 likely depends on the production of SARS-CoV-2 binding plasma cells and memory B cells after infection or vaccination. Previous work has shown evidence that germinal center reactions, a critical component of the B cell response, are disrupted in severe COVID-19. This may adversely affect protective immunity from re-infection. Consistent with an extrafollicular B cell response, severe COVID-19 patients have large scale changes in B cell populations such as elevated frequencies of clonally expanded, class switched, unmutated plasmablasts. However, it is not clear whether mild or asymptomatically infected individuals show similar differences in B cell repertoires. Here, we use single cell RNA sequencing of B cells to show that, in contrast to hospitalized COVID-19 patients, mildly symptomatic COVID-19 subjects have B cell repertoires skewed towards clonally diverse, somatically hypermutated memory B cells approximately 30 days after the onset of symptoms. This provides evidence that B cell responses are less disrupted in mild COVID-19, and that the infection resolves with the production of memory B cells.

Antibody profile in patients with mild and severe leptospirosis

Project description:Leptospirosis is zoonotic disease of global importance, with over a million cases andnearly 60,000 deaths annually. Symptomatic disease presentation ranges from a mildfebrile disease with non-specific symptoms to severe forms, characterized by multi-organ failure, lung hemorrhage, and death. Factors governing severe outcomes remainunclear, but the host immune response likely plays an important role. In the presentstudy, we applied high throughput techniques to identify the antibody profiles ofpatients with severe and mild leptospirosis. We discovered a limited number ofimmunodominant antigens, specific to patients. Surprisingly, we found the antibodyrepertoire varies in patients with different clinical outcomes and hypothesized thatpatients with mild symptoms were protected from severe disease due to pre-existingantibodies, while the profile of patients with severe outcomes was representative of afirst exposure. These findings represent a substantial step forward in the knowledge ofthe humoral immune response to Leptospira infection, and we have identified newtargets for vaccine and diagnostic test development.

Paired whole blood human transcription profiles from children with severe malaria and mild malaria

Project description:Whole blood transcriptomes from a longitudinal study of 5 Malawian children who first present with severe Plasmodium falciparum malaria, and return in one month with mild malaria We used microarrays to identify transcripts that were associated with each clinical presentation. A blood sample was taken upon presentation during the severe and mild malaria episodes in 5 Malawian children (total n=5 pairs) followed by RNA extraction and hybridization on Affymetrix GeneChip Human Gene 1.0 ST Array, using a paired analysis

Demultiplexing Ig repertoires by parallel mRNA/DNA sequencing shows major differential alterations in severe COVID-19

Project description:To in-depth analyze the anti-SARS-CoV-2 humoral response and find elements that can lead or prevent acute respiratory distress syndrome (ARDS), we dissected the multiple layers of B cell responses by NGS immunoglobulin repertoires on RNA template from peripheral blood cell of severe COVID-19 patients.

Unbiased quantification of immunoglobulin diversity at the DNA level with VDJ-seq

Project description:For high-throughput sequencing and quantification of immunoglobulin repertoires, most methodologies utilise RNA. However, output varies enormously between recombined genes due to different promoter strengths and differential activation of lymphocyte subsets, precluding quantitation of recombinants on a per cell basis. To date, DNA-based approaches have used V gene primer cocktails, with substantial inherent biases. Here we describe VDJ-seq, which accurately quantitates immunoglobulin diversity at the DNA level in an unbiased manner. This is accomplished with a single primer extension step using biotinylated J gene primers. By addition of unique molecular identifiers (UMI) before primer extension, we reliably remove duplicate sequences and correct for sequencing and PCR errors. Furthermore, VDJ-seq captures productive and non-productive VDJ and DJ recombination events on a per cell basis. Library preparation takes 3 days, with 2 days of sequencing, and 1 day of data processing and analysis.

Mild, moderate and severe enterovirus 71 (EV71) isolates infection in human PBMCs

Project description:Hand, foot and mouth disease (HFMD), caused by enterovirus 71 (EV71), presents mild to severe disease, and sometimes fatal neurological and respiratory manifestations. However, reasons for the severe pathogenesis remain undefined. To investigate this, infection and viral kinetics of EV71 isolates from clinical disease (mild, moderate and severe) from Sarawak, Malaysia, were characterized in human rhabdomyosarcoma (RD), neuroblastoma (SH-SY5Y) and peripheral blood mononuclear cells (PBMCs). High resolution transcriptomics was used to decipher EV71-host interactions in PBMCs. Ingenuity analyses revealed similar pathways triggered by all EV71 isolates, although the extent of activation varied. Importantly, several pathways were found to be specific to the severe isolate, including triggering receptor expressed on myeloid cells 1 (TREM-1) signaling. Depletion of TREM-1 in EV71-infected PBMCs with peptide LP17 resulted in decreased levels of pro-inflammatory genes, and reduced viral loads for the moderate and severe isolates. Mechanistically, this is the first report describing the transcriptome profiles during EV71 infections in primary human cells, and the involvement of TREM-1 in the severe disease pathogenesis, thus providing new insights for future treatment targets.
