For over a decade, Immune Regulation News has been keeping the scientific community up-to-date with the latest research and reviews related to immune regulation. Key research areas covered include the roles of regulatory T cells (Treg cells) in autoimmunity and self-reactivity, as well as immune response to disease, transplantation and cancer. We also provide vital updates on the latest jobs and upcoming events in the field of immunology.

The Immuno-Reactivity of Polypseudorotaxane Functionalized Magnetic CDMNP-PEG-CD Nanoparticles

Nanoparticles were assessed in vivo for retention, bio-distribution and immunoreactivity. Cyclodextrin molecules via polyethylene glycol induced a temporary blood monocyte response and was cleared effectively from the body through the urine system in mice.

Modification of Proteins by Metabolites in Immunity

Scientists review the recent findings in post-translational modifications in macrophages and T cells and speculate whether they could be of use in the effort to develop therapeutics for immune-related diseases.

Bispecific Antibody Inhalation Therapy for Redirecting Stem Cells from the Lungs to Repair Heart Injury

CD34‐CD42b platelet‐targeting bispecific antibodies were designed to simultaneously recognize HSCs and platelets. After inhalation delivery, PT‐BsAbs reached the lungs and conjoined HSCs and platelets.

The E3 Ubiquitin Ligase Peli1 Regulates the Metabolic Actions of mTORC1 to Suppress Antitumor T Cell Responses

Researchers identified the E3 ubiquitin ligase Peli1 as an important regulator of T cell metabolism and antitumor immunity. Peli1 ablation profoundly promotes tumor rejection, associated with increased tumor‐infiltrating CD4 and CD8 T cells.

High-Dose per Fraction Radiotherapy Induces Both Anti-Tumor Immunity and Immunosuppressive Responses in Prostate Tumors

Scientists studied the effects of high-dose per fraction radiotherapy with and without anti-Gr-1 using syngeneic murine allograft prostate cancer models. The dynamic change of immune populations, including tumor-infiltrating lymphocytes, T-regulatory cells, and myeloid-derived suppressive cells was evaluated using flow cytometry and immunohistochemistry.

RIPK1 Expression Associates with Inflammation in Early Atherosclerosis in Humans and Can be Therapeutically Silenced to Reduce NF-κB Activation and Atherogenesis in Mice

Researchers examined expression of RIPK1 protein and mRNA in both human and mouse atherosclerotic lesions, and using loss-of-function approaches in vitro in macrophages and endothelial cells to measure inflammatory responses. They administered weekly injections of RIPK1 anti-sense oligonucleotides to Apoe-/- mice fed a cholesterol-rich diet for eight weeks.

Small-Molecule-Induced Polymerization Triggers Degradation of BCL6

Scientists report an alternative mechanism of targeted protein degradation, in which a small molecule induced the highly specific, reversible polymerization of a target protein, followed by its sequestration into cellular foci and subsequent degradation.
