Sepsis-trained macrophages promote antitumoral tissue-resident T cells.

Sepsis induces immune alterations, which last for months after the resolution of illness. The effect of this immunological reprogramming on the risk of developing cancer is unclear. Here we use a national claims database to show that sepsis survivors had a lower cumulative incidence of cancers than matched nonsevere infection survivors.

Monocyte Signature Associated with Herpes Simplex Virus Reactivation and Neurological Recovery after Brain Injury.

Brain injury induces systemic immunosuppression, increasing the risk of viral reactivations and altering neurological recovery. To determine if systemic immune alterations and lung replication of herpesviridae are associated and can help predict outcomes after brain injury. We collected peripheral blood mononuclear cells in patients with severe brain injury requiring invasive mechanical ventilation.

Phase I/II Multicenter Trial of a Novel Therapeutic Cancer Vaccine, HepaVac-101, for Hepatocellular Carcinoma.

Purpose: Immunotherapy for hepatocellular carcinoma (HCC) shows considerable promise in improving clinical outcomes. HepaVac-101 represents a single-arm, first-in-human phase I/II multicenter cancer vaccine trial for HCC (NCT03203005). It combines multipeptide antigens (IMA970A) with the TLR7/8/RIG I agonist CV8102.

Circulating Regulatory T Cells Expressing Tumor Necrosis Factor Receptor Type 2 Contribute to Sepsis-Induced Immunosuppression in Patients During Septic Shock.

Background: Septic shock remains a major cause of death that can be complicated by long-term impairment in immune function. Among regulatory T (Treg) cells, the tumor necrosis factor receptor 2 positive (TNFR2pos) Treg-cell subset endorses significant immunosuppressive functions in human tumors and a sepsis mouse model but has not been investigated during septic shock in humans.

Methods: We prospectively enrolled patients with septic shock hospitalized in intensive care units (ICU).
