MaveDB 2024: a curated community database with over seven million variant effects from multiplexed functional assays.

Multiplexed assays of variant effect (MAVEs) are a critical tool for researchers and clinicians to understand genetic variants. Here we describe the 2024 update to MaveDB ( https://www.mavedb.

Meropenem-resistant Burkholderia pseudomallei: a concerning single case in Australia with no prior meropenem exposure.

We report a case of cutaneous melioidosis in a 54-year-old male with a meropenem-resistant sub-population. He was empirically treated with episodic doxycycline and trimethoprim-sulfamethoxazole; however, the abscess re-accumulated. The patient had no prior exposure to meropenem.

Diverse Epithelial Lymphocytes in Zebrafish Revealed Using a Novel Scale Biopsy Method.

Zebrafish (Danio rerio) are a compelling model for studying lymphocytes because zebrafish and humans have similar adaptive immune systems, including their lymphocytes. Antibodies that recognize zebrafish proteins are sparse, so many investigators use transgenic, lymphocyte-specific fluorophore-labeled lines. Human and zebrafish lymphocyte types are conserved, but many aspects of zebrafish lymphocyte biology remain uninvestigated, including lymphocytes in peripheral tissues, like epidermis.

The axillary lymphoid organ - an external, experimentally accessible immune organ in the zebrafish.

Lymph nodes and other secondary lymphoid organs play critical roles in immune surveillance and immune activation in mammals, but the deep internal locations of these organs make it challenging to image and study them in living animals. Here, we describe a previously uncharacterized external immune organ in the zebrafish ideally suited for studying immune cell dynamics , the axillary lymphoid organ (ALO). This small, translucent organ has an outer cortex teeming with immune cells, an inner medulla with a mesh-like network of fibroblastic reticular cells along which immune cells migrate, and a network of lymphatic vessels draining to a large adjacent lymph sac.
