Brief Summary
The protocol is to draw peripheral blood from healthy volunteers for in vitro studies. The aims of these in vitro studies are to determine the cellular and intracellular mechanisms by which hypertonic saline and ATP release regulate neutrophil and lymphocyte functions.

Outcome Measures
Primary Outcomes (1)
Immune cells will be studied in vitro to learn about basic mechanisms of immune cell signaling.
The purpose of this study is to obtain blood from healthy subjects (volunteers) for in vitro studies to explore how immune cells function. Cells will be isolated and subjected to various tests including stimuli that simulate immune cell activation in health and disease. Subjects will not be subjected to any treatments. Only some of the cells (leukocytes) in the blood will be studied. For example, activation events such as cytokine production, the ability of leukocytes (=immune cells) to detect and respond to bacterial products will be assessed. No identifiable information about study subjects will be kept.
Blood is collected as needed; time frame: indefinitely. Blood used between 1-7 days after blood draws.
Interventions
No drugs or interventions are given. Single purpose is to draw blood from healthy subjects to study immune cell biology in vitro. No records about subjects to be kept.
Eligibility Criteria

Biospecimen
Blood is collected from all subjects in the same fashion. Purpose: isolation of immune cells for in vitro studies of cell function. This is an observational study in human beings in predefined groups of individuals who are healthy and volunteer to donate blood for laboratory science studies. Subjects in the study receive neither diagnostic, therapeutic, nor other interventions, and the investigator does not assign specific interventions to any of the subjects of the study.
