Antibody Responses against Pneumocystis jirovecii in Health Care Workers Over Time

Emerging Infectious Diseases, 2013
In a previous cross-sectional study, we showed that clinical staff working in a hospital had significantly higher antibody levels than nonclinical staff to Pneumocystis jirovecii.

Activated immune cells present a lung interstitial‐to‐airway/alveolar cross‐compartment sharing pattern in severe pneumonia

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
The interstitial‐to‐airway cross‐compartment sharing pattern of activated immune cells provides new insights for severe pneumonia. Macrophages could amplify local immune response by recruiting specific activated immune cells via CXCL10–CXCR3 signalling into airway, while other immune cells reside with limited inflammatory activity.

Torque Teno Virus in Bronchoalveolar Lavage Fluid of Hematological Patients and Association With Pathogens

Journal of Medical Virology, Volume 98, Issue 5, May 2026.
ABSTRACT Torque teno virus (TTV) replication is tightly modulated by the host immune response. As such, TTV viremia has been investigated as a biomarker of immune competence for monitoring the risks of allograft rejection and opportunistic infections in solid organ transplant recipients.

Efficacy of upadacitinib induction for pediatric inflammatory bowel disease

JPGN Reports, Volume 7, Issue 2, Page 296-300, May 2026.
Abstract Objectives Upadacitinib, a second‐generation Janus kinase (JAK) inhibitor, is approved for moderate to severe Crohn's disease (CD) and ulcerative colitis (UC) in adults. Its efficacy in pediatric patients remains unclear, though early reports suggest benefits in refractory inflammatory bowel disease (IBD).

Outbreaks of Pneumocystis Pneumonia in 2 Renal Transplant Centers Linked to a Single Strain of Pneumocystis: Implications for Transmission and Virulence [PDF]

, 2017
By restriction fragment length polymorphism analysis, 2 outbreaks of Pneumocystis pneumonia in renal transplant patients in Europe were shown to be caused by the same strain of Pneumocystis; another outbreak in Japan was caused by a different ...

Treosulfan–fludarabine conditioning in infants with severe combined immunodeficiencies: Extended study of the UK paediatric treosulfan study

British Journal of Haematology, Volume 208, Issue 5, Page 1713-1723, May 2026.
Summary Allogeneic haematopoietic stem cell transplantation (HSCT) is a curative therapy for severe combined immunodeficiency (SCID). Conditioning improves donor engraftment and freedom from immunoglobulin replacement (IgR) but increases the risks of acute and late toxicity. Treosulfan, a reduced toxicity alkylating agent, has emerged as an alternative
