(Submitter supplied) Staphylococcus aureus is a pathogenic bacterium but also a commensal of skin and anterior nares in humans. As S. aureus transits from skins/nares to inside the human body, it experiences changes in temperature. The production and content of S. aureus extracellular vesicles (EV) have been increasingly studied over the past few years and EVs are increasingly being recognized as important to the infectious process. more...

(Submitter supplied) Staphylococcus aureus is an opportunistic pathogen that colonizes the anterior nares of about 30-50% of the population. Colonization is most often asymptomatic, however, self-inoculation through inhalation, ingestion, or an open wound, can give rise to potentially fatal infections of the deeper tissues and blood. Like all bacteria, S. aureus is able to sense and respond to environmental cues and modify gene expression to adapt to specific environmental conditions. more...

(Submitter supplied) Staphylococcus aureus is Gram-positive commensal bacteria that can also cause human disease ranging from mild, self-resolving skin infections to life-threatening conditions like endocarditis, osteomyelitis, and septicemia. Previously we demonstrated a role for the S. aureus sRNA, Teg41 in regulating production of the alpha Phenol Soluble Modulin toxins (αPSMs). In this study, we further characterize the regulatory role of Teg41. more...

(Submitter supplied) Microglia are resident immune cells of the brain that play important roles in mediating inflammatory responses in several neurological diseases via direct and indirect mechanisms. One indirect mechanism may involve extracellular vesicle (EV) release, so that the molecular cargo transported by microglia-derived EVs can have functional effects by facilitating intercellular communication. The molecular composition of microglia-derived EVs, and how microglial activation states impacts EV composition and EV-mediated effects in neuroinflammation, remain poorly understood. more...

(Submitter supplied) Lipoproteins of the opportunistic pathogen Staphylococcus aureus play a crucial role in various cellular processes and host interactions. Consisting of a protein and a lipid moiety, they support nutrient acquisition and anchor the protein to the bacterial membrane. Recently, we identified several processed and secreted small linear peptides that derive from the secretion signal sequence of S. aureus lipoproteins. more...

(Submitter supplied) Mycobacterium tuberculosis (Mtb) secretes pathogenicity factors and immunologically active molecules via membrane vesicles. However, nothing is known about the mechanisms involved in mycobacterial vesicle biogenesis. This study investigates molecular determinants of membrane vesicle production in Mtb by analyzing Mtb cells under conditions of high vesicle production: iron limitation and VirR restriction. more...

(Submitter supplied) To look for transcriptomic changes that resulted in membrane vesicle biogenesis, we performed RNA sequencing on S.sanguinis in different culture and community conditions We then examined three separate differential expression analyses, as well as correlated the phenotypic vesicle quantification with normalized count data across all samples.

(Submitter supplied) Formation of extracellular vesicles (EVs) has emerged as a novel paradigm in cell-to-cell communication in health and disease. We performed a comparative analysis of steady-state (ssEVs) and cell death-associated EVs (cdEVs) following apoptosis (apoEVs), necroptosis (necEVs), and ferroptosis (ferEVs) using the same cell line. For each EV type, we systematically determined the biophysical and biochemical characteristics, the protein cargo, and the presence of methylated ribosomal RNA. more...
