Article Synopsis
  • The immune mechanisms behind synovitis and joint damage in rheumatoid arthritis (RA) are still not well understood, particularly the role of CD8 T cells, which have been found in higher numbers in RA patients.
  • Researchers conducted advanced single-cell analysis and T cell receptor sequencing on CD8 T cells from the blood of RA patients with anti-citrullinated protein antibodies (ACPA) to explore their functionality.
  • They discovered two distinct CD8 T cell subpopulations: one that aggressively targets citrullinated autoantigens and is linked to joint damage, and a second smaller memory population that plays a different role, suggesting a complex contribution to the disease process.

Introduction: Sepsis is a common, potentially life-threatening complication of infection. The optimal treatment for sepsis includes prompt antibiotics and intravenous fluids, facilitated by its early and accurate recognition. Currently, clinicians identify and assess severity of suspected sepsis using validated clinical scoring systems.

This paper reviews the natural and treated history of hepatitis C virus infection, the interactions between current therapies and anaesthesia medications, and the implications of occupational exposure and infection to anaesthetists in light of significant changes in treatment. In the past decade, the introduction of new direct acting antiviral medications has seen high cure rates with a sustained viral response across all virus genotypes. These medications are well tolerated with minimal side-effects.

Background: While all salivary glands (SGs) can be involved in primary Sjögren's syndrome (pSS), their respective role in pathogenesis remains unclear. Our objective was to assess immunopathway activation in paired parotid and labial gland tissue from biopsy-positive and biopsy-negative pSS and non-SS sicca patients.

Methods: Paraffin-embedded, paired parotid and labial salivary gland tissue and peripheral blood mononuclear cells were obtained from 39 pSS and 20 non-SS sicca patients.

In angiosperms, meiotic failure coupled with the formation of genetically unreduced gametophytes in ovules (apomeiosis) constitute major components of gametophytic apomixis. These aberrant developmental events are generally thought to be caused by mutation. However, efforts to locate the responsible mutations have failed.
