  Lupus nephritis is a common severe manifestation of systemic lupus erythematosus. Despite recent advances in therapeutics and understanding of its pathogenesis, there are still substantial unmet needs. This review discusses recent discoveries in these areas, especially the role of tubulointerstitial inflammation (TII) in lupus nephritis.
 
  Non-white ethnicity is still a major risk and poor prognostic factor in lupus nephritis. TII and fibrosis have been found to be associated with worse renal outcome but the current lupus nephritis treatment guidelines and trials are based on the degree of glomerular inflammation. In combination with mycophenolate mofetil, a B-cell-targeted therapy (belimumab) and a calcineurin inhibitor (voclosporin) have shown efficacy in recent lupus nephritis trials. However, response rates have been modest. While lupus glomerulonephritis results from immune complex deposition derived from systemic autoantibodies, TII arises from complex processes associated with in situ adaptive cell networks. These include local antibody production, and cognate or antigen-induced interactions between T follicular helper cells, and likely other T-cell populations, with antigen presenting cells including B cells, myeloid dendritic cells and plasmacytoid dendritic cells.
 
  Better understanding of the pathogenesis of TII will identify novel therapeutic targets predicted to improve outcomes in our patients with lupus nephritis.

  Aberrations in the innate and in the adaptive arms of the immune system play both important roles in the initiation and progression of systemic lupus erythematosus (SLE).  https://www.selleckchem.com/products/LAQ824(NVP-LAQ824).html  The aim of this study was to provide an update on the most recent findings on the cellular pathogenesis of SLE. Our overview focused particularly on results obtained over the last 18 months.
 
  Recent observations have provided an improved understanding of the importance of low-density granulocytes, a highly proinflammatory subset of neutrophils. We also highlighted in this work recent descriptions of the various cellular sources associated with the interferon signature. In addition, novel contributions have also developed our understanding of the potential importance of extrafollicular T-B-cell interactions in SLE pathogenesis. Finally, the role of recently described B and T-cell subsets, that is, atypical memory B cells, T-peripheral helper cells, and Th10 T cells, were also reviewed.
 
  Recent findings in the cellular pathogenesis of SLE give a deeper comprehension of previously described mechanisms which drive SLE pathogenesis and shed light on novel players in immune dysregulation that could help to identify potential therapeutic targets.

  This review highlights the available data describing racial and ethnic health disparities among patients with rheumatoid arthritis in the United States from an epidemiological, disease activity, and wider socioeconomic standpoint.
 
  Despite centralized government initiatives to include more underrepresentative minority populations into research, many of the studies that examined rheumatoid arthritis still fail to include sizeable cohorts of races or ethnic groups other than whites. Evidence is slowly mounting that individual, provider, and system-level barriers exist and contribute to unequal care that leads to poorer outcomes amongst patients with rheumatoid arthritis. As rheumatoid arthritis is a progressive disease, early treatment is crucial to delay functional decline - a narrow window for many minority patients who are disproportionality affected by disability.
 
  To combat the inequality that exists amongst rheumatoid arthritis patients we must focus on why discrepancies exist on every level, system, physician, patient, and illness. Further research is needed to tease the complex interplay between race, social economic status, medical access, and outcomes to explain the disparities found in rheumatoid arthritis.

  This review discusses the coronavirus disease-2019 (COVID-19) Global Rheumatology Alliance (GRA), the reason for its formation, the challenges with running the registry, and future opportunities for global collaborative research in rheumatology.
 
  The GRA has been successful in collecting and publishing a large volume of case data on patients with rheumatic disease with COVID-19. In addition, the GRA has published reviews, opinion pieces, and patient-directed summaries of research to further assist in disseminating timely and accurate information about COVID-19 in rheumatic diseases. There have been numerous challenges in the journey but they have been addressed through a collaborative problem-solving approach.
 
  The initial objectives of the GRA to describe the outcomes in patients with rheumatic disease who developed COVID-19 have been achieved. There has been extensive use of the data in the clinic and also to try and understand the mechanisms of disease and opportunities for drug repurposing. There remain numerous important areas for research which the GRA will continue to pursue as the pandemic evolves.
