Not all plasma cells are made equal: well-hidden layers of heterogeneity.
Review in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plasma cells (PCs) are the final stage of B cell development and sustain long-term humoral immunity by continuously secreting antibodies. Once considered a homogeneous population defined by a short-lived versus long-lived dichotomy, PCs are now recognised as highly heterogeneous. Recent advances have overturned several dogmas, revealing that long-lived plasma cells (LLPCs) can arise from diverse B cell precursors, and persist in tissues beyond the bone marrow. PC heterogeneity is shaped by intrinsic factors, including B cell origin, antigen affinity, BCR signalling strength and immunoglobulin isotype, as well as extrinsic factors such as tissue-specific microenvironments, cytokines and cellular interactions at induction and maintenance sites. Furthermore, temporal variables, termed "Moment", including age, sex, and inflammatory status, modulate PC fate throughout their maturation. This process also plays a central role in the emergence of heterogeneity within these LLPCs. Together, these parameters define a dynamic, context-dependent PC landscape with significant implications for immune regulation and vaccine design.
