Long Term Follow Up of a Family with A3243G Mitochondrial Syndrome.

Purpose: To describe the clinical and multimodal imaging (MMI) features of a family (proband, sister and mother) with A3243G mitochondrial retinopathy and long-term follow up.

Methods: Medical and imaging records were retrospectively evaluated. Multimodal imaging included ultra-widefield color fundus photography, fundus autofluorescence, and spectral-domain optical coherence tomography.

A LysM and SH3-domain containing region of the Listeria monocytogenes p60 protein stimulates accessory cells to promote activation of host NK cells.

Listeria monocytogenes (Lm) infection induces rapid and robust activation of host natural killer (NK) cells. Here we define a region of the abundantly secreted Lm endopeptidase, p60, that potently but indirectly stimulates NK cell activation in vitro and in vivo. Lm expression of p60 resulted in increased IFNγ production by naïve NK cells co-cultured with treated dendritic cells (DCs).
