ABSTRACT Microbes evolve within complex ecological communities where biotic interactions impact both individual cells and the environment as a whole. Here we examine how cellular regulation in the marine cyanobacterium Prochlorococcus is influenced b

An important determinant of disease following Streptococcus pneumoniae (pneumococcus) lung infection is pulmonary inflammation mediated by polymorphonuclear leukocytes (PMNs). We found that upon intratracheal challenge of mice, recruitment of PMNs in

Aging Cell
Extracellular adenosine production by CD73 and signaling via A1 adenosine receptors is crucial for the ability of PMNs to kill engulfed Streptococcus pneumoniae. Aging is accompanied by changes in the extracellular adenosine pathway on PMNs which res

Streptococcus pneumoniae (pneumococcus) resides asymptomatically in the nasopharynx but can progress from benign colonizer to lethal pulmonary or systemic pathogen. Both viral infection and aging are risk factors for serious pneumococcal infections.

SummaryThe elderly are susceptible to serious infections by Streptococcus pneumoniae (pneumococcus), which calls for a better understanding of the pathways driving the decline in host defense in aging. We previously found that extracellular adenosine

The Atlantic and Pacific Oceans represent different biogeochemical regimes in which the abundant marine cyanobacterium Prochlorococcus thrives. We have shown that Prochlorococcus populations in the Atlantic are composed of hundreds of genomically, an

Prochlorococcus is the smallest oxygenic phototroph in the ocean, where it can be found in great abundance throughout the euphotic zone in mid-latitude waters. Populations of this picocyanobacterium have been observed below the euphotic zone, but the

Utilization of nitrate as a nitrogen source is broadly conserved among marine phytoplankton, yet many strains of Prochlorococcus lack this trait. Among cultured strains, nitrate assimilation has only been observed within two clades of Prochlorococcus

Carbon Budding in the Ocean Bacterial vesicles are gaining increasing attention for their roles in pathogenesis, but the abundance of these structures and their ecological roles in nonpathogenic contexts have received little notice. Biller et al. (p.
