What is Zap-70 Deficiency?

The ZAP-70 (zeta-associated protein 70) deficiency is characterized by an impaired T-cell activation, which is caused by a malfunction of signal transduction. ZAP-70 deficiency is a primary immunodeficiency disease which includes cellular immune deficiencies. Inheritance occurs as an autosomal recessive. The ZAP-70 protein plays an essential role in T-cell signaling and T cell selection in the thymus. A ZAP-70 deficiency leads to defects in T cell activation. Patients with ZAP-70…

Wheezing: Causes and Treatment

Wheezing is a relatively high-pitched whistling sound, which is generated by the movement of air through constricted or compressed small airways. It is both a symptom and auscultation, Longer expiratory phase wheezing. The air flow through a constricted or compressed segment of small airway becomes turbulent, resulting in vibrations of the airway walls. This vibration generates the sound of wheezing. Wheezing occurs more frequently during expiration because of increased intrathoracic…
