Efficacy of DYRK1A inhibitors in novel models of Down syndrome acute lymphoblastic leukemia

Despite significant advances, outcomes for children with Down syndrome (DS, trisomy 21) who develop acute lymphoblastic leukemia remain poor. Reports of large DS-ALL cohorts have shown that children with DS have inferior event-free survival and overall survival compared to children without DS.

Murine bone-derived mesenchymal stem cells undergo molecular changes after a single passage in culture

The rarity of the mesenchymal stem cell (MSC) population poses a significant challenge for MSC research. Therefore, these cells are often expanded in vitro, prior to use. However, long-term culture has been shown to alter primary MSC properties.

Delivery of PEGylated liposomal doxorubicin by bispecific antibodies improves treatment in models of high-risk childhood leukemia

High-risk childhood leukemia has a poor prognosis because of treatment failure and toxic side effects of therapy. Drug encapsulation into liposomal nanocarriers has shown clinical success at improving biodistribution and tolerability of chemotherapy. However, enhancements in drug efficacy have been limited because of a lack of selectivity of the liposomal formulations for the cancer cells.

Immunisation with the BCG and DTPw vaccines induces different programs of trained immunity in mice

In addition to providing pathogen-specific immunity, vaccines can also confer nonspecific effects (NSEs) on mortality and morbidity unrelated to the targeted disease. Immunisation with live vaccines, such as the BCG vaccine, has generally been associated with significantly reduced all-cause infant mortality. In contrast, some inactivated vaccines, such as the diphtheria, tetanus, whole-cell pertussis (DTPw) vaccine, have been controversially associated with increased all-cause mortality especially in female infants in high-mortality settings.

RUNX2 regulates leukemic cell metabolism and chemotaxis in high-risk T cell acute lymphoblastic leukemia

T cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignancy with inferior outcome compared with that of B cell ALL. Here, we show that Runt-related transcription factor 2 (RUNX2) was upregulated in high-risk T-ALL with KMT2A rearrangements (KMT2A-R) or an immature immunophenotype. In KMT2A-R cells, we identified RUNX2 as a direct target of the KMT2A chimeras, where it reciprocally bound the KMT2A promoter, establishing a regulatory feed-forward mechanism.

Maternal HIV infection alters antimicrobial immunity in exposed and uninfected infants

Implementation of lifelong ART of all HIV-infected women has the potential to improve maternal determinants of protective immunity in the young infant

Optimized peripheral blood progenitor cell mobilization for autologous hematopoietic cell transplantation in children with high-risk and refractory malignancies

Our approach to hematopoietic progenitor cells mobilization resulted in highly effective HPC harvest in children and adolescents with high-risk cancers

Influenza epidemiology in patients admitted to sentinel Australian hospitals in 2018: the Influenza Complications Alert Network (FluCAN)

This report summarises the epidemiology of hospitalisations with laboratory-confirmed influenza during the 2018 influenza season

Molecular Epidemiology of Noninvasive and Invasive Group A Streptococcal Infections in Cape Town

There is low coverage of the multivalent M protein vaccine in our setting, emphasizing the need to reformulate the vaccine to improve coverage

COVID-19 in WA: Why having our kids wear masks at school is the correct call

West Australian children as young as Year 3 are now turning up to school in masks, presenting a new challenge for kids, parents and schools.
