The inhibitory effect of an antiserum to surface protein P50 of Babesia gibsoni on the growth of the parasite was determined with severe combined immunodeficiency mice given canine red blood cells. The antiserum to the recombinant P50 protein significantly inhibited the parasite growth, indicating that P50 might be a useful vaccine candidate.

Communications between different cell types within a tissue are often critical for the proper functioning of an organ. In the central nervous system, interactions among neurons and glial cells are known to modulate neurotransmission, energy metabolism, extracellular ion homeostasis, and neuroprotection. Here we showed that bradykinin, a proinflammatory neuropeptide, can be detected by astrocytes, resulting in the secretion of cytokines that act on neurons.

The interaction of Mesomycoplasma (Mycoplasma) ovipneumoniae (M. ovipneumoniae) with host cells is a pivotal step in the infection process, underlining the necessity to develop vaccines and therapeutic approaches targeting the pathogen's key invasion mechanisms. The bacterium's capacity for adherence, invasion, and subsequent evasion of the host immune response underpins its pathogenicity, rendering adherence genes feasible vaccine targets.

Article Synopsis
  • The study investigates the cytokine profile of IL-25 and IL-35 in patients with amoebiasis, an intestinal disease caused by a parasite, in southern Iraq.
  • Conducted from August 2022 to May 2023, it included 80 participants, 50 with amoebiasis confirmed by PCR and 30 healthy controls.
  • Results showed that IL-25 levels were significantly higher in patients with the infection compared to controls, suggesting it could serve as a diagnostic marker for amoebiasis, while IL-35 levels did not differ significantly.

Article Synopsis
  • Understanding how the immune system responds to SARS-CoV-2 is essential for developing effective treatments and understanding long-term immunity.
  • The study focused on measuring specific antibody responses (anti-RBD IgG) in unvaccinated individuals recovered from COVID-19 in Cuba, using ELISA methods to quantify antibody levels.
  • Findings indicated that those who experienced severe illness had significantly higher antibody levels and blocking abilities, while the antibody response generally declined over four months, showing that severity of disease is a key factor in the immune response.
