How the IL-2 receptor β-chain specifically shapes immunity has remained enigmatic. In this issue of JEM, Zhang et al. (https://doi.org/10.1084/jem.20182304) and Fernandez et al. (https://doi.org/10.1084/jem.20182015) independently report the first observations of autosomal recessive mutations in IL2RB, revealing a requirement for IL2RB in immunity and peripheral immune tolerance.

Design Example: Maintaining Level of an Embankment

Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Role of Vitamins in Maintaining Bone Health

The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Active versus Passive Immunity01:31

Active versus Passive Immunity

Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.
Active Immunity
Active immunity refers to the resistance one develops...

Introduction to Lymphatic and Immune System

Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are...
