Do all monocytes/macrophages in mice express F4/80? 


Best insight from top research papers

Not all monocytes/macrophages in mice express F4/80. Research indicates that in the context of late-stage colorectal liver metastasis (CRLM), Ly6C+ CD11b+ F4/80- monocytes transform into Ly6C- CD11b int F4/80+ cells within the tumor microenvironment . Additionally, in Angiotensin II-induced hypertension (AHT), a subpopulation of renal macrophages (Mo) with a CD11c+F4/80+ phenotype was observed, suggesting a distinct phenotype from other monocytes/macrophages . Furthermore, myeloid-lineage cells in response to mechanical loading differentiate into CD68+ F4/80+ macrophages, which play a role in periosteal bone formation, indicating a specific subset expressing F4/80 . These findings collectively suggest that while some monocytes/macrophages express F4/80, not all monocytes/macrophages in mice exhibit this marker, highlighting the heterogeneity within these immune cell populations.

Is CDK4 expressed or present in macrophages?3 answersCDK4 is expressed in macrophages. Yang et al. identified CDK4 as one of the key proteins in the network influenced by tumor-associated macrophages (TAMs) in ovarian carcinoma cells. Peckert-Maier et al. showed that CD83, a marker for pro-resolving alternatively activated macrophages (AAM), is important for the phenotype and function of these macrophages. Furudate et al. investigated the involvement of TAMs in different stages of mycosis fungoides (MF) and found that periostin, a stromal factor, affects the mRNA expression of chemokines and MMPs in macrophages. Sypek and Wyler demonstrated that membrane-associated TNF on CD4+ T cells, which are effector cells in defense against Leishmania major, is involved in the activation of antileishmanial defense in macrophages. Li et al. showed that VSIG4, exclusively expressed on macrophages, plays a role in renal tubulointerstitial injury and inhibits T cell infiltration.
Does the literature mention a way to induce CDK4 expression in macrophages or monocytes?5 answersThe literature does mention a way to induce CDK4 expression in macrophages or monocytes. It has been found that p21 and cyclin D1 act cooperatively as activators of Cdk4 through the release of cyclin-dependent kinase inhibitors (CKIs) of the INK4 family. Additionally, the activation of CD4 via interaction with major histocompatibility complex class II (MHC-II) triggers cytokine expression and the differentiation of human monocytes into functional mature macrophages. This suggests that CD4 ligation can induce macrophage differentiation of monocytes, which may have implications for HIV infection and persistence in the macrophage compartment.

How do JAK/STAT Inhibitors affect dendritic cells or antigen presenting cells?
5 answers
JAK/STAT inhibitors, such as ruxolitinib and TG101348, have varying effects on dendritic cells (DCs) and antigen-presenting cells. Ruxolitinib, a less selective JAK1/2 inhibitor, profoundly impairs NK-cell function by blocking downstream pSTAT5, affecting their ability to secrete IFNγ or lyse targets. In contrast, TG101348, a JAK2-specific inhibitor, shows less functional compromise in stimulated NK cells, inhibiting only soluble IL15-mediated STAT5 phosphorylation. Additionally, tofacitinib, a JAK inhibitor, impacts the differentiation of human DCs, reducing their differentiation into immature DCs and favoring the generation of M1-like pro-inflammatory macrophages, characterized by enhanced production of IL-12 and IL-23. These findings highlight the complex and cell-specific effects of JAK/STAT inhibitors on DCs and antigen-presenting cells.

What is the link between SLC16A2 and protein synthesis?
4 answers
The SLC16A family, including SLC16A2, plays a crucial role in cellular metabolism and transport mechanisms that indirectly influence protein synthesis. SLC16A2 encodes the monocarboxylate transporter 8 (MCT8), primarily known for its specific role in thyroid hormone (TH) transport, which is essential for normal brain development and metabolic regulation. Thyroid hormones are critical regulators of gene expression, metabolic processes, and, by extension, protein synthesis. They influence the transcription of genes involved in the metabolic pathway, thereby affecting the availability of amino acids, the building blocks of proteins. Moreover, the SLC16A family members, such as SLC16A1, are involved in the transport of monocarboxylates like lactate and pyruvate across the plasma membrane, which are key metabolites in cellular energy metabolism. The energy status of a cell, regulated by monocarboxylate transporters, is fundamental to protein synthesis, as the process requires significant energy input. For instance, SLC16A1's role in tumor metabolism and its association with cancer progression and metastasis indirectly highlights the importance of energy metabolism in supporting the biosynthetic demands of rapidly proliferating cells, including protein synthesis. Furthermore, the interaction of SLC16A family transporters with other cellular mechanisms, such as pH regulation and fluid transport, underscores their contribution to creating an optimal intracellular environment for various biochemical processes, including protein synthesis. The regulation of intracellular pH is particularly important for maintaining enzyme activities that are crucial for protein synthesis. In summary, while SLC16A2's direct link to protein synthesis is not explicitly detailed in the provided contexts, its role in TH transport and the broader involvement of the SLC16A family in metabolic regulation and cellular homeostasis suggest an indirect but significant influence on protein synthesis through the regulation of metabolic pathways and maintenance of cellular energy status.
