Isolation of Functional Cardiac Immune Cells

15.5K
This method for isolating functional immune cells from the heart provides an alternative to the conventional methods of collagenase digestion, which causes unwanted immune cell activation, resulting in a decreased responsiveness of these cells. Our method of isolation yields functional cardiac immune cells by avoiding problems associated with enzymatic...

Studying Organelle Dynamics in B Cells During Immune Synapse Formation

9.6K
Herein we describe two approaches to characterize cell polarization events in B lymphocytes during the formation of an IS. The first, involves quantification of organelle recruitment and cytoskeleton rearrangements at the synaptic membrane. The second is a biochemical approach, to characterize changes in composition of the centrosome, which undergoes polarization to the immune synapse.

Summary

Aging impairs immune function, increasing risks of disease and mortality in the elderly. Understanding immunosenescence versus adaptive immune changes is key to mitigating these effects.

Area of Science:

  • Gerontology and Immunology

Background:

  • Aging leads to a decline in immune system integrity, affecting the control of infections, autoimmunity, and cancer.
  • The aging immune system exhibits a complex profile, with some functions declining while others, like heightened inflammation, may become detrimental.

Purpose of the Study:

  • To differentiate between age-related immune decline (immunosenescence) and reversible immune adaptations in the elderly.

Main Methods:

  • This study reviews existing literature on the aging immune system.
  • Analysis focuses on contrasting the characteristics of immunosenescence with adaptive immune responses in older adults.

Main Results:

  • Immunosenescence is characterized by a progressive loss of immune function.
  • Certain immune responses in the elderly, such as increased cytokine production and inflammation, represent adaptations that can be harmful.

Conclusions:

  • Distinguishing between irreversible immunosenescence and potentially reversible immune adaptations is crucial for understanding aging-related health risks.
  • Targeting these adaptive immune changes may offer strategies to improve healthspan in older populations.
