Early-Onset Autoimmunity Associated with SOCS1 Haploinsufficiency

By whole-exome/genome sequencing scientists identified heterozygous, autosomal-dominant, germline loss-of-function mutations in the SOCS1 gene in ten patients from five unrelated families with early onset autoimmune manifestations.

A Trispecific Killer Engager Molecule Against CLEC12A Effectively Induces NK-Cell Mediated Killing of AML Cells

To target acute myeloid leukemia blasts and leukemic stem cells using natural killer (NK) cells, scientists developed a trispecific killer engager molecule containing a humanized anti-CD16 heavy chain camelid single-domain antibody that activates NK cells.

Exosomal LGALS9 in the Cerebrospinal Fluid of Glioblastoma Patients Suppressed Dendritic Cell Antigen Presentation and Cytotoxic T-Cell Immunity

Researchers found that glioblastoma multiforme-cerebrospinal fluid-exosomes (GBM-CSF-Exos) contained a unique protein, LGALS9 ligand, which bound to the TIM3 receptor of dendritic cells (DCs) in the CSF to inhibit antigen recognition, processing and presentation by DCs, leading to failure of the cytotoxic T-cell-mediated antitumor immune response.

Mesenchymal Stem Cells: a Potential Treatment Approach for Refractory Chronic Spontaneous Urticaria

Scientists found that the T cell subsets and inflammatory molecules were not affected by MSC treatment during the follow-up period. In control patients, a significant decrease was detected only at the Th2 subset, TGF-β1, PGE2, IDO and anti-FcεRI levels on the 14th day of treatment.

TGF-β Suppresses Type 2 Immunity to Cancer

The authors showed that depletion of transforming growth factor-β receptor 2 (TGFβR2) in CD4+ T cells, but not CD8+ T cells, halts cancer progression as a result of tissue healing and remodeling of the blood vasculature, causing cancer cell hypoxia and death in distant avascular regions.

Identification of Immune Landscape Signatures Associated with Clinical and Prognostic Features of Hepatocellular Carcinoma

Investigators combined immune landscape signatures with hepatocellular carcinoma clinical and prognostic features to classify them into distinct subtypes. The immunogenomic profiles, stromal cell features and immune cell composition of the subtypes were then systematically analyzed.
