The complete absence of the critical role of B cells in the final differentiation of T cells into memory lineages could be a major oversight in modern immunology. In this short essay, I will try to summarize some of the published evidence showing that T cell differentiation into memory cells is triggered only by B cells in germinal centers after priming at infection sites for CD8 T cells and in the T cell zone for CD4 T cells in the spleen and draining lymph nodes.

Central to the immunopathology of both diseases is the disruption of the balance between regulatory T cells (Tregs) and T helper 17 (Th17) cells, an equilibrium that governs tissue homeostasis versus inflammatory destruction. Polyamines, principally putrescine (PUT), spermidine (SPD), and spermine (SPN), are emerging as critical immunometabolic regulators that modulate the plasticity and functional identity of both cell populations. Dysbiosis, particularly the enrichment of microbial communities that drive aberrant polyamine biosynthesis through ornithine decarboxylase (ODC)-dependent pathways, generates a polyamine-rich microenvironment that further dysregulates T cell function and promotes sustained inflammation. Experimental evidence demonstrates that mucosal polyamine levels correlate with dysbiosis, dysfunctional Treg (TregDys) expansion, and CD4<sup>+</sup>CD4<sup>+</sup>T cell hyperactivation, collectively contributing to and perpetuating chronic inflammation. The striking parallels between periodontitis and IBD reinforce the existence of conserved mechanisms linking mucosal dysbiosis to polyamine-driven immune dysregulation, with shared therapeutic implications for targeting the dysbiosis-T cell-polyamine axis to restore immune homeostasis.

LAM arises from inherited or spontaneous mutations in <i>TSC1</i> or <i>TSC2</i> genes, which result in constitutive activation of mTOR and downstream signaling. These mutations arise in a uterine population of cells that migrate to the lungs where they establish nodules that progress to cysts and progressive lung function decline. Clinically, an elevated level (>800 pg/ml) of vascular endothelial growth factor -D (VEGF-D) is a definitive diagnostic marker for LAM. Recent work by our group and others highlights the role of immune dysfunction in the establishment and progression of LAM. A subset of natural killer (NK) cells in LAM express the VEGF-D receptors, VEGFR3 and NRP2. These distinct NK cells are responsive to VEGF-D treatment and LAM NK cells have altered NKG2D and CD160 expression, as well as changes in phosphorylation of STAT4(Y693) and ERK1/2 (Y202/S204). Phosphorylation of these proteins increases after VEGF-D treatment at short time points (0-30 min) and longer time points (up to 6 hours). In addition, the signaling kinetics are altered compared to cytokine stimulation. Increased IFNγ production was shown by ELISA and flow cytometry after VEGF-D, and other cytokines. Baseline IFNγ expression is higher in LAM NK cells, and LAM NK cells elaborate IFNγ when stimulated with VEGF-D. Additionally, these NK cells have increased responsiveness to IL12/33 and decreased responsiveness to IL12/IL27 co-stimulation.
