AI Article Synopsis

  • Innate lymphoid cells (ILCs) and macrophages are vital tissue-resident immune cells that maintain tissue health and regulate immune responses, primarily located at barrier surfaces in mammals.
  • ILCs respond to changes in the environment, infections, and tissue damage, while also influencing macrophage development and function, highlighting a complex interplay between these two cell types.
  • Further research is needed to understand their interactions in different tissues, especially during inflammation and disease, which could lead to new therapeutic strategies for improving human health.

Article Abstract

Innate lymphoid cells (ILCs) and macrophages are tissue-resident cells that play important roles in tissue-immune homeostasis and immune regulation. ILCs are mainly distributed on the barrier surfaces of mammals to ensure immunity or tissue homeostasis following host, microbial, or environmental stimulation. Their complex relationships with different organs enable them to respond quickly to disturbances in environmental conditions and organ homeostasis, such as during infections and tissue damage. Gradually emerging evidence suggests that ILCs also play complex and diverse roles in macrophage development, homeostasis, polarization, inflammation, and viral infection. In turn, macrophages also determine the fate of ILCs to some extent, which indicates that network crossover between these interactions is a key determinant of the immune response. More work is needed to better define the crosstalk of ILCs with macrophages in different tissues and demonstrate how it is affected during inflammation and other diseases. Here, we summarize current research on the functional interactions between ILCs and macrophages and consider the potential therapeutic utility of these interactions for the benefit of human health.

Background: The phosphodiesterase 4 (PDE4) inhibitor apremilast downregulates the production of IL-23 and other pro-inflammatory cytokines involved in the pathogenesis of psoriatic arthritis (PsA).

Aim: To investigate the effects of apremilast on the production of cytokines by peripheral blood monocyte-derived macrophages, innate-like lymphocyte cells (ILCs), mucosal-associated invariant T (MAIT) cells, γδ T cells, natural killer (NK) cells, and NKT-like cells from patients with PsA manifesting different clinical responses to the treatment.

Methods: Peripheral blood samples were obtained from patients with PsA at baseline and after 1 and 4 months of apremilast therapy (n = 23) and 20 controls with osteoarthritis.

Eosinophilic esophagitis (EoE) is a chronic allergic disorder characterized by eosinophilia and epithelial thickening, resulting in dysphagia. While emerging evidence implicates increased frequencies of group 2 innate lymphoid cells (ILC2s) and increased interleukin (IL)-33 expression in EoE pathogenesis, the precise mechanisms remain unclear. In this study, we investigated the role of ILC2s in EoE pathogenesis.

is an emerging multi-drug-resistant fungal pathogen that colonizes the skin and causes invasive infections in hospitalized patients. Multi-cellular aggregative phenotype is widely reported in the isolates, but its role in skin colonization and host immune response is not yet known. In this study, we generated aggregative phenotype by deleting the gene in and determined the fungal colonization and host immune response using an intradermal mouse model of skin infection.

This Optimized Multiparameter Immunofluorescence Panel (OMIP) reports on the development of a mass cytometry panel for broad immunophenotyping of leukocytes from bronchoalveolar lavage from rhesus macaques. Using this panel, we were able to identify myeloid populations such as macrophages, neutrophils, monocytes, myeloid and plasmacytoid DCs, basophils and lymphoid cell lineages including B cells, natural killer (NK) cells, mucosal associated invariant T (MAIT) cells, γδ T cells, CD4 T cells, CD8 β T cells, CD8 T cells, and innate lymphoid cells (ILCs). We also included markers for defining memory, differentiation (CCR7, CD28, CD45RA), homing potential (CXCR3), cytotoxic potential (perforin, granzyme B, granzyme K), cell activation/differentiation (HLA-DR, CD69, IgD) and effector function (CD154, IFN-γ, TNF, IL-2, IL-17A, IL-6, IL-1β, CCL4 and CD107a).

Sarcoidosis is a multiorgan granulomatous disease that lacks diagnostic biomarkers and targeted treatments. Using blood and skin from patients with sarcoid and non-sarcoid skin granulomas, we discovered that skin granulomas from different diseases exhibit unique immune cell recruitment and molecular signatures. Sarcoid skin granulomas were specifically enriched for type 1 innate lymphoid cells (ILC1s) and B cells and exhibited molecular programs associated with formation of mature tertiary lymphoid structures (TLSs), including increased CXCL12/CXCR4 signaling.
