The histopathological picture of Toxoplasma gondü RH strain (virulent) and Beverley strain (a virulent) was experimentally studied in mice. Nearly all the internal organs and tissues showed pathological changes ranging between the mild congestion to the severe degeneration. However, the changes were more serious in mice infected with RH strain than those infected with Beverley strain. The lungs showed massive consolidation and severe congestion. The heart showed hyaline degeneration of a cardiac muscle fibers. Focal areas of necrosis were seen in the liver, spleen and kidneys which were enlarged as well as in the cerebral cortex of the brain. The bone marrow and skeletal muscles were infiltrated by mononuclear inflammatory cells. The eyes showed mononuclear inflammatory cells in the retina consisted mainly of lymphocytes and the photo receptors were damaged. In congenital toxoplasmosis the brain showed perivascular mononuclear inflammatory infiltrate as well as multiple areas of necrosis. Microglial nodules were sometimes seen. The eyes showed no pathological lesion.

Background: Sepsis is regarded as a dysregulated immune response to infections. Recent study showed partially reversal of immunosuppression by trained immunity, which fosters an enhanced immune response towards a secondary challenge. However, the role of trained immunity in sepsis has not been fully understood.

Platelet-rich fibrin (PRF) and Enamel Matrix Derivatives (EMD) can support the local regenerative events in periodontal defects. There is reason to suggest that PRF and EMD exert part of their activity by targeting the blood-derived cells accumulating in the early wound healing blastema. However, the impact of PRF and EMD on blood cell response remains to be discovered.

Background: Type 2 Diabetes Mellitus (T2DM) represents a major global health challenge, marked by chronic hyperglycemia, insulin resistance, and immune system dysfunction. Immune cells, including T cells and monocytes, play a pivotal role in driving systemic inflammation in T2DM; however, the underlying single-cell mechanisms remain inadequately defined.
Methods: Single-cell RNA sequencing of peripheral blood mononuclear cells (PBMCs) from 37 patients with T2DM and 11 healthy controls (HC) was conducted.

Introduction: The innate immune response is an important first checkpoint in the evolution of an infection. Although adaptive immunity is generally considered the immune component that retains antigenic memory, innate immune responses can also be affected by previous stimulations. This study evaluated the impact of vaccination on innate cell activation by TLR7/8 agonist R848, as well as seasonal variations.
