Natural killer (NK) cells are an appealing off-the-shelf, allogeneic cellular therapy due to their cytotoxic profile. However, their activity against solid tumors remains suboptimal in part due to the upregulation of NK-inhibitory ligands, such as HLA-E, within the tumor microenvironment. Here, we utilize CRISPR-Cas9 to disrupt the KLRC1 gene (encoding the HLA-E-binding NKG2A receptor) and perform non-viral insertion of a GD2-targeting chimeric antigen receptor (CAR) within NK cells isolated from human peripheral blood.

Disruption of this homeostasis leads to numerous skin disorders. Human and animal skin differ significantly, limiting the translational potential of animal-based investigations to advance therapeutics to human skin diseases.

However, the specific role of neutrophils during tumor development, and their interactions with other immune cells is still not well understood. Here, we use both standard well plate culture and an under oil microfluidic (UOM) assay with an integrated ECM bridge to elucidate how naive primary neutrophils respond to tumor cells.

- * The research found that tissue samples from patients showed strong IFN-I (a type of immune response) activity and signs of inflammation, even when the virus was only minimally present in biopsies.
- * Additionally, an experiment using hamsters demonstrated that while the virus was active in the lungs, local IFN-I responses occurred in other areas (like toes) without the body developing traditional immunity to the virus, suggesting a potential viral trigger for some pernio cases.
Objective: To review the congenital anomalies of the pancreas with their main clinical manifestations and key imaging findings on CT and MRI.
Background And Clinical Significance: Anomalies of pancreatic development are frequent and generally asymptomatic, but can mimic and predispose individuals to pancreatic or peripancreatic pathologies, such as pancreatitis or malignancy. Their correct diagnosis may help avoid unnecessary further investigations and procedures, or establish adequate treatment when they manifest clinically.
