Assessing neutrophil subsets in autoimmune disease: Moving away from relying on density?Neutrophils are the most abundant immune cell in circulation. However, due to a number of technical challenges for researchers, including the neutrophil's short lifespan and difficulties with preservation, they are often discarded during blood processing and thus ignored in cohort studies. As such, the contribution of neutrophils to disease and their involvement in disease mechanisms is less explored compared with other immune cell types.

Editorial: The relationship between puberty and immune-driven diseaseThe way the immune system operates differs between males and females. This is due to both differential expression of immune-related genes from the sex chromosomes as well as the immune modulatory properties of sex hormones. Together, these effects contribute to a skewed prevalence of disease and disease course between males and females, including allergic-, infectious-, autoimmune-, and cancerous disease.

Probiotic peanut oral immunotherapy versus oral immunotherapy and placebo in children with peanut allergy in Australia (PPOIT-003): a multicentre, randomised, phase 2b trialOral immunotherapy is effective at inducing desensitisation to allergens and induces sustained unresponsiveness (ie, clinical remission) in a subset of patients, but causes frequent reactions. We aimed to investigate whether addition of a probiotic adjuvant improved the efficacy or safety of peanut oral immunotherapy.

Targeting the mucosal immune system in a mouse model to prevent pregnancy complications following maternal bacterial infectionThis work is the first step to develop safe treatments for pregnant mums to protect against preterm delivery and low birth weight caused by maternal infections.

Two-year post-treatment outcomes following peanut oral immunotherapy in the Probiotic and Peanut Oral Immunotherapy-003 Long-Term (PPOIT-003LT) studyFew studies have examined long-term outcomes following oral immunotherapy; none have examined long-term risks and benefits associated with distinct clinical outcomes (desensitization, remission).

An infant mouse model of influenza-driven nontypeable Haemophilus influenzae colonization and acute otitis media suitable for preclinical testing of novel therapiesNontypeable Haemophilus influenzae (NTHi) is a major otitis media (OM) pathogen, with colonization a prerequisite for disease development. Most acute OM is in children <5 years old, with recurrent and chronic OM impacting hearing and learning. Therapies to prevent NTHi colonization and/or disease are needed, especially for young children. Respiratory viruses are implicated in driving the development of bacterial OM in children.

In Vivo Evidence of Respiratory Syncytial Virus Persistence in a Subset of Pulmonary Dendritic Cells Following a Primary InfectionRespiratory syncytial virus (RSV) causes annual epidemics of infections affecting the whole population. In vitro, it has been shown to infect and persist in human dendritic cells (DCs) for prolonged periods. Initially persistence is associated with low levels of replication before the virus becomes dormant. Reactivation of viral replication can be triggered many months later.

Biomarker signatures for progressive idiopathic pulmonary fibrosisIdiopathic Pulmonary Fibrosis (IPF) is a progressive lung disease in which circulatory biomarkers has the potential for guiding management in clinical practice. We assessed the prognostic role of serum biomarkers in three independent IPF cohorts, the Australian IPF Registry (AIPFR), Trent Lung Fibrosis (TLF) and Prospective Observation of Fibrosis in the Lung Clinical Endpoints (PROFILE).

Prebiotic Supplementation During Pregnancy Modifies the Gut Microbiota and Increases Metabolites in Amniotic Fluid, Driving a Tolerogenic Environment In UteroThe gut microbiota is influenced by environmental factors such as food. Maternal diet during pregnancy modifies the gut microbiota composition and function, leading to the production of specific compounds that are transferred to the fetus and enhance the ontogeny and maturation of the immune system. Prebiotics are fermented by gut bacteria, leading to the release of short-chain fatty acids that can specifically interact with the immune system, inducing a switch toward tolerogenic populations and therefore conferring health benefits.
