Not all plasma cells are made equal: well-hidden layers of heterogeneity

1

Plasma cells (PCs) are crucial for humoral immunity, producing antibodies and representing the final stage of B cell maturation.
2

Recent findings reveal that long-lived plasma cells (LLPCs) are heterogeneous and can originate from various B cell precursors.
3

PC heterogeneity is influenced by intrinsic factors like B cell lineage and extrinsic factors such as tissue microenvironments and cytokines.
4

Temporal factors, including age and inflammatory conditions, significantly affect the development and destiny of plasma cells.
5

Understanding PC biology is essential for developing strategies to modulate antibody responses in health and disease.
