Nerve Growth Factor Regulation by TNF-α and IL-1β in Synovial Macrophages and Fibroblasts in Osteoarthritic Mice by Shotaro Takano, Kentaro Uchida, Masayuki Miyagi, Gen Inoue, Hisako Fujimaki, Jun Aikawa, Dai Iwase, Atsushi Minatani, Kazuya Iwabuchi, Masashi Takaso

“…To investigate the role of macrophages as a regulator and producer of nerve growth factor (NGF) in the synovial tissue (ST) of osteoarthritis (OA) joints, the gene expression profiles of several inflammatory cytokines in the ST, including synovial macrophages and fibroblasts, of OA mice (STR/Ort) were characterized. …”

Deletion of sphingosine 1-phosphate receptor 1 in myeloid cells reduces hepatic inflammatory macrophages and attenuates MASH by Gopanandan Parthasarathy, Nanditha Venkatesan, Guneet Singh Sidhu, Myeong Jun Song, Chieh-Yu Liao, Fanta Barrow, Amy Mauer, Tejasav Sehrawat, Yasuhiko Nakao, P. Vineeth Daniel, Debanjali Dasgupta, Kevin Pavelko, Xavier S. Revelo, Harmeet Malhi

“…We have previously demonstrated that pharmacological sphingosine 1-phosphate (S1P) receptor modulation ameliorates MASH and is associated with attenuated accumulation of intrahepatic macrophage and T-cell subsets. Although S1P receptors are expressed on several immune cell types, given the prominent role of monocyte-derived recruited macrophages in the sterile inflammation of MASH, we hypothesized that deletion of S1P receptor 1 (S1P1) on myeloid cells may ameliorate MASH by reducing the accumulation of proinflammatory monocyte-derived macrophages in the liver. …”

Early precursor-derived pituitary gland tissue-resident macrophages play a pivotal role in modulating hormonal balance by Henna Lehtonen, Heli Jokela, Julian Hofmann, Lauriina Tola, Arfa Mehmood, Florent Ginhoux, Burkhard Becher, Melanie Greter, Gennady G. Yegutkin, Marko Salmi, Heidi Gerke, Pia Rantakari

“…Importantly, all pitMØs originate from early yolk sac progenitors and maintain themselves through self-renewal, independent of bone marrow-derived monocytes. Macrophage depletion experiments unveil the role of macrophages in regulating intrapituitary hormonal balance through extracellular ATP-mediated intercellular signaling. …”
