Safety, pharmacokinetic, immunogenicity, and pharmacodynamic responses in healthy volunteers following a single intravenous injection of purified staphylococcal protein A.

A single-dose study was conducted to characterize the safety, pharmacokinetic, immunogenicity, and pharmacodynamic activity of highly purified Staphylococcal protein A (SPA), a native bacterial protein with immune-modulatory activity. Twenty healthy adults received a single intravenous dose of either 0.3 µg/kg (n = 8) or 0.

K12/SECTM1, an interferon-γ regulated molecule, synergizes with CD28 to costimulate human T cell proliferation.

CD7 is a cell-surface molecule, expressed on T lymphocytes and NK cells, which functions as a costimulatory receptor for T cell proliferation. SECTM1 has been proposed as a ligand for CD7. However, the expression pattern of this molecule in human immune cells and role in human T cell function remain unclear.

Mouse embryonic stem cell adherent cell differentiation and cytotoxicity (ACDC) assay.

An adherent cell differentiation and cytotoxicity (ACDC) assay was developed using pluripotent J1 mouse embryonic stem cells (mESCs). Adherent mESCs were used to evaluate chemical-induced effects on both stem cell viability and differentiation using an in-cell western technique after a 9-day culture. DRAQ5/Sapphire700 stains were used to quantify cell number.

Early pregnancy peripheral blood gene expression and risk of preterm delivery: a nested case control study.

Background: Preterm delivery (PTD) is a significant public health problem associated with greater risk of mortality and morbidity in infants and mothers. Pathophysiologic processes that may lead to PTD start early in pregnancy. We investigated early pregnancy peripheral blood global gene expression and PTD risk.
