Impaired Generation of High-Affinity Memory B Cells and Neutralizing Antibodies Against SARS-CoV-2 in Adolescents and Young Adults With Juvenile Idiopathic Arthritis Treated With Tumor Necrosis Factor Inhibitors. [PDF]

ACR Open Rheumatol
Objective We evaluated the immunogenicity of SARS‐CoV‐2 mRNA vaccines in patients with juvenile idiopathic arthritis (JIA), focusing on the generation of spike‐specific memory B cells (MBCs) and of neutralizing antibodies, and assessed the impact of disease‐modifying antirheumatic drugs, particularly tumor necrosis factor inhibitors (TNFi).

Psychosine Alleviates Colitis via Inhibiting Th1 and Th17 Cell Immune Responses in Inflammatory Bowel Diseases

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background Aberrant T‐helper 1 (Th1) and Th17 cell activation is involved in the pathogenesis of inflammatory bowel disease (IBD). Psychosine is known to induce apoptosis, promote astrocyte activation, and inhibit osteoclastogenesis. However, the role of psychosine on Th1 and Th17 cell immune responses has not been previously reported. In this

A comparison of super‐resolution microscopy techniques for imaging tightly packed microcolonies of an obligate intracellular bacterium

Journal of Microscopy, EarlyView.
Abstract Conventional optical microscopy imaging of obligate intracellular bacteria is hampered by the small size of bacterial cells, tight clustering exhibited by some bacterial species and challenges relating to labelling such as background from host cells, a lack of validated reagents, and a lack of tools for genetic manipulation.

3D morphological analysis of age and sex‐related changes in human cortical bone remodeling spaces using micro‐CT

Journal of Anatomy, EarlyView.
This study investigates human cortical bone remodeling space morphology and its relationship with age and sex using micro‐CT imaging. Remodeling space morphology exhibits great inter‐ and intraindividual variation. Its dimensions decrease with increasing age, but do not differ between sexes.

Herpesvirus Simplex Virus‐1 Exploits Inflammation to Infect Periodontal Stem Cells and Disrupt Lineage Commitment

Journal of Periodontal Research, EarlyView.
HSV‐1 infects oral mesenchymal stem cells both in vitro and in vivo to dysregulate their lineage commitment. An inflamed gingival environment increases susceptibility to HSV‐1 infection, which further elevates proinflammatory cytokine levels and exacerbates alveolar bone loss.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.
