Six marine bacterial isolates were obtained from fluid and sediments collected at alkaline serpentinite mud volcanoes of the Mariana forearc to examine life at high pH in a marine environment. Here, we present the draft genome sequences of these six isolates, classified as strains of the species .

Follicular lymphoma (FL) is an indolent non-Hodgkin lymphoma of germinal center origin, which presents with significant biologic and clinical heterogeneity. Using RNA-seq on B cells sorted from 87 FL biopsies, combined with machine-learning approaches, we identify 3 transcriptional states that divide the biological ontology of FL B cells into inflamed, proliferative, and chromatin-modifying states, with relationship to prior GC B cell phenotypes. When integrated with whole-exome sequencing and immune profiling, we find that each state was associated with a combination of mutations in chromatin modifiers, copy-number alterations to TNFAIP3, and T follicular helper cells (Tfh) cell interactions, or primarily by a microenvironment rich in activated T cells.

Article Synopsis
  • Deep-sea hydrothermal vents enrich microbial food webs through chemolithoautotrophic activity, with microbial eukaryotes, or protists, playing key roles as consumers and sources of nutrition.
  • Research was conducted at the Von Damm and Piccard vent fields to measure microbial eukaryotic cell abundance and predation pressure, revealing higher cell counts and grazing rates under deep-sea conditions compared to standard atmospheric conditions.
  • The study illustrated a significant relationship between grazing rates, prey cell abundance, and the temperature of hydrothermal fluids, emphasizing the role of protists in sustaining local carbon export and nutrient supply in the deep ocean.
