Granulomas, organized aggregates of immune cells which form in response to (), are characteristic but not exclusive of tuberculosis (TB). Despite existing investigations on TB granulomas, the determinants that differentiate host-protective granulomas from granulomas that contribute to TB pathogenesis are often disputed. Thus, the goal of this narrative review is to help clarify the existing literature on such determinants.

Sirtuins are the major players in host immunometabolic regulation. However, the role of sirtuins in the modulation of the immune metabolism pertaining to salmonellosis is largely unknown. Here, our investigation focussed on the role of two important sirtuins, SIRT1 and SIRT3, shedding light on their impact on intracellular 's metabolic switch and pathogenesis establishment.

Allogeneic stem cell transplantation (alloSCT) provides a curative treatment option for hematological malignancies. After HLA-matched alloSCT, donor-derived T cells recognize minor histocompatibility antigens (MiHAs), which are polymorphic peptides presented by HLA on patient cells. MiHAs are absent on donor cells due to genetic differences between patient and donor.

Potassium ions (K) released from dying necrotic tumour cells accumulate in the tumour microenvironment (TME) and increase the local K concentration to 50 mM (high-[K]). Here, we demonstrate that high-[K] decreases expression of the T-cell receptor subunits CD3ε and CD3ζ and co-stimulatory receptor CD28 and thereby dysregulates intracellular signal transduction cascades. High-[K] also alters the metabolic profiles of T-cells, limiting the metabolism of glucose and glutamine, consistent with functional exhaustion.

Background And Aims: Epidemiological studies have associated reduced bacterial diversity and abundance and food allergy. This mechanistic review investigated the link between gut dysbiosis and food allergy with a focus on the role of short-chain fatty acids (SCFAs) in modulating T-cells. T-cell differentiation poses an opportunity to direct the immune cells towards an anergic regulatory T cell (Treg) or allergic T helper 2 (Th2) response.
