Acute Neuroinflammatory Response in the Substantia Nigra Pars Compacta of Rats after a Local Injection of Lipopolysaccharide by Yazmin M. Flores-Martinez, Manuel A. Fernandez-Parrilla, Jose Ayala-Davila, David Reyes-Corona, Victor M. Blanco-Alvarez, Luis O. Soto-Rojas, Claudia Luna-Herrera, Juan A. Gonzalez-Barrios, Bertha A. Leon-Chavez, Maria E. Gutierrez-Castillo, Irma A. Martínez-Dávila, Daniel Martinez-Fong

“…At this time, evidence of neurodegeneration could be seen, entailing decreased tyrosine hydroxylase (TH) immunoreactivity, irregular body contour, and prolongation discontinuity of TH+ cells, as well as apparent phagocytosis of TH+ cells by OX42+ cells. Altogether, these results show that LPS evokes a typical inflammatory response in the substantia nigra that is followed by dopaminergic neurodegeneration.…”

Rap1 and mTOR signaling pathways drive opposing immunotoxic effects of structurally similar aryl-OPFRs, TPHP and TOCP by Bilin Zhao, Shuang Zheng, Gaoxiang Yang, Zhijun He, Jiewei Deng, Lijuan Luo, Xinyan Li, Tiangang Luan

“…TPHP reduced GTP levels necessary for Rap1 activation, thereby inhibiting phagocytosis and adhesion of THP-1 macrophages. Conversely, TOCP stimulated the mTOR signaling pathway, enhancing phosphorylation of downstream proteins S6K, RHOA, and PKC, consequently promoting immune responses. …”

Cigarette smoke compromises macrophage innate sensing in response to pneumococcal infection by Wei-Chih Liao, Chia-Huei Chou, Mao-Wang Ho, Jo-Tsen Chen, Shu-Ling Chou, Yu-Tsen Huang, Ngoc-Niem Bui, Hui-Yu Wu, Chi-Fan Lee, Wei-Chien Huang, Chih-Ho Lai

“…Moreover, CSE disrupts macrophage polarization and impedes innate immune signaling to suppress pneumococcal phagocytosis by macrophages. Conclusion: Our results provide evidence that CS manipulates the signaling molecules to subvert macrophage functions, thereby hindering the innate response against pneumococcal infection.…”

Adoptive cell transfer of piezo-activated macrophage rescues immunosuppressed rodents from life-threating bacterial infections by Xiaoyi Liu, Wenxiu Xu, Junkun Feng, Ying Wang, Kai Li, Yi Chen, Wenjun Wang, Weiwei Zhao, Shaohua Ge, Jianhua Li

“…We show that piezoNPs strongly interact with macrophages within subcutaneous abscesses caused by Staphylococcus aureus (S. aureus) infections, and demonstrate that this interaction enhances the macrophage-mediated antibacterial phagocytosis and killing activity through intracellular piezocatalysis. …”

Dose-dependent serological profiling of AdCLD-CoV19-1 vaccine in adults by Jung Hyuk Lee, Yuna Shin, Kwang-Soo Shin, Ju Yeon Park, Mi Sun Kim, Young-Shin Park, Wuhyun Kim, Joon Young Song, Ji Yun Noh, Hee Jin Cheong, Chang-Yuil Kang, Sang Hwan Seo, Jae-Ouk Kim, Deok Ryun Kim, Nathaniel S. Hwang, Jae Seung Yang, Jerome H. Kim, Byoung-Shik Shim, Manki Song

“…Moreover, univariate and multivariate analyses revealed that the high-dose vaccine induced higher levels of S2-specific antibodies binding to FcγR2A and FcγR3B, closely associated with antibody-dependent neutrophil phagocytosis (ADNP). Further analysis using the Omicron BA.2 variant demonstrated that the high-dose group maintained significantly higher levels of IgG and FcγR3B binding to the S2 antigen and exhibited a significantly higher ADNP response for the S2 antigen compared with the low-dose group. …”

Brucella suis ΔmapB outer membrane vesicles as an acellular vaccine against systemic and mucosal B. suis infection by Florencia Muñoz González, Florencia Muñoz González, Magali G. Bialer, Maria L. Cerutti, Silvia M. Estein, Lila Y. Ramis, Pablo C. Baldi, Pablo C. Baldi, Ángeles Zorreguieta, Ángeles Zorreguieta, Mariana C. Ferrero, Mariana C. Ferrero

“…Serum antibodies from both OMVs groups reduced B. suis adherence and invasion of lung epithelial cells and enhanced its phagocytosis by macrophages. Upon in vitro antigen stimulation, spleen cells from mice immunized with ΔmapB OMVs secreted higher levels of interleukin-17 and especially gamma interferon compared to cells from mice immunized with wt OMVs, suggesting the induction of a stronger T helper 1 response in the ΔmapB OMVs group. …”
