Cytokine Profile in Early Infection by Leptospira interrogans in A/J Mice by Lorena Bavia, Íris A. de Castro, Mariane Tami Amano, Ana Maria Gonçalves da Silva, Silvio Arruda Vasconcellos, Lourdes Isaac

“…Since rodents are at the same time the main reservoir and generally asymptomatic to Leptospira infection, understanding why some animal species are resistant and others are susceptible to this infection would shed some light in how to control this important zoonosis. The innate immune response against Leptospira is mainly dependent on phagocytosis and activation of the Complement System. …”

Suppression of Proinflammatory Cytokines and Mediators in LPS-Induced RAW 264.7 Macrophages by Stem Extract of Alternanthera sessilis via the Inhibition of the NF-κB Pathway by Katyakyini Muniandy, Sivapragasam Gothai, Khaleel M. H. Badran, S. Suresh Kumar, Norhaizan Mohd Esa, Palanisamy Arulselvan

“…Inflammation is a natural process of the innate immune system, accompanied with the increase in the level of proinflammatory mediators, for example, nitric oxide (NO) and prostaglandin (PGE2); cytokines such as interleukin 6 (IL-6), interleukin 1β (IL-1β), and tumor necrosis factor alpha (TNFα); and enzymes including inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) via the activation and nuclear translocation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) subunit p65 due to the phosphorylation of inhibitory protein, IκBα. …”

Role of outer membrane vesicles of hypervirulent Klebsiella pneumoniae isolated from bovine uterine discharge in pro-inflammatory dysregulation by A. F. Daham, A. H. Jaber, A. Neamah, H. Al-Karagoly

“…Notably, incubating THP-1 cells with high con-centrations of hvKP OMVs inhibited IL-1β and TNF responses, indicating that these OMVs may not only facilitate the internalisation of the bacterium by THP-1 cells but also suppress the cells’ innate immune response to hvKP infection. This ability of hvKP OMVs to evade the immune system and modulate host responses contributes significantly to the bacterium’s pathogenicity.…”
