Memory B cells play a fundamental role in host defenses against viruses, but to date, their
role has been relatively unsettled in the context of SARS-CoV-2. We report here a longitudinal …

In addition to serum immunoglobulins, memory B cell (MBC) generation against severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) is another layer of immune protection, …

The SARS-CoV-2 Omicron variant can escape neutralization by vaccine-elicited and
convalescent antibodies. Memory B cells (MBCs) represent another layer of protection against …

How infection by a viral variant showing antigenic drift impacts a preformed mature human
memory B cell (MBC) repertoire remains an open question. Here, we studied the MBC …

Objective To investigate the association of air pollution exposure with the severity of
interstitial lung disease (ILD) at diagnosis and ILD progression among patients with systemic …

Immune thrombocytopenia (ITP) is an acquired bleeding disorder mediated by pathogenic
autoantibodies secreted by plasma cells (PCs) in many patients. In refractory ITP patients, the …

Patients with AAT are often initially misdiagnosed as having immune thrombocytopenia (ITP)
but do not usually respond to ITP first-line therapy (ie corticosteroids [CS] and intravenous …

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis characterized
by the infiltration of various tissues by CD68-positive (+), CD1a-negative (–) spumous …

Objectives This work aimed to study the prevalence and risk factors associated with well-being
and career satisfaction among French internal medicine physicians and residents. …

Memory B cells (MBCs) represent a second layer of immune protection against SARS-CoV-2.
Whether MBCs elicited by mRNA vaccines can recognize the Omicron variant is of major …
