Removal of CD276+ Cells from Haploidentical Memory T-Cell Grafts Significantly Lowers the Risk of GVHD

Analysis of CD45RA-depleted haploidentical mixed lymphocytes culture revealed insufficient suppression of alloresponses in the CD4+ compartment and identified CD276 as a marker for alloreactive memory Th1 T cells.

DNMT3A Haploinsufficiency Causes Dichotomous DNA Methylation Defects at Enhancers in Mature Human Immune Cells

The authors demonstrated that DNMT3A haploinsufficiency impaired the gain of DNA methylation at decommissioned enhancers, while simultaneously and unexpectedly impairing DNA demethylation of newly activated enhancers in mature human myeloid cells.

Neutralizing Antibody Responses to SARS-CoV-2 in Symptomatic COVID-19 Is Persistent and Critical for Survival

The presence of neutralizing antibodies within the first weeks from symptoms onset correlated with time to a negative swab result, while the lack of neutralizing capacity correlates with an increased risk of a fatal outcome.

Asymmetric Cell Division Shapes Naive and Virtual Memory T Cell Immunity during Aging

Investigators found that aging, known to negatively impact immune responses, impaired asymmetric cell division in murine CD8+ T cells, and that this phenotype could be rescued by transient mTOR inhibition.

Dual Vaccination against IL-4 and IL-13 Protects against Chronic Allergic Asthma in Mice

Investigators developed conjugate vaccines against mouse IL-4 and IL-13, and demonstrated their prophylactic and therapeutic efficacy in reducing IgE levels, AHR, eosinophilia and mucus production in mouse models of asthma analyzed up to 15 weeks after initial vaccination.
