Trypanosoma cruzi, the etiological agent of Chagas' disease, can infect both phagocytic and non-phagocytic cells. T. cruzi gp82 and gp90 are cell surface proteins belonging to Group II trans-sialidases known to be involved in host cell binding and invasion.

Background: The mitogen-activated protein kinase (MAPK)/ERK signaling cascade and the phosphoinosytol-3 phosphate/Akt (PI3K/Akt) pathways are involved in proliferation and differentiation of hematopoietic cells. The frequency of PI3K/Akt and MAPK pathway activation in adult acute lymphoblastic leukemia (ALL) still need to be elucidated.

Aims: To assess the activity and prognostic implications of MAPK/ERK and PI3K/Akt pathways in adult (ALL).

Article Synopsis
  • In early 2020, a major symptom of COVID-19 was loss of smell (anosmia), affecting 60-70% of cases, often appearing alongside other symptoms and lasting for months after recovery.
  • Research indicates SARS-CoV-2 may spread from the respiratory system to the brain via olfactory receptors, as the virus binds to ACE2 and TMPRSS2 in sustentacular cells of the olfactory epithelium.
  • A study of 102 hospitalized patients found 17.6% with anosmia and 9.8% with ageusia, revealing a correlation between gene expression levels and ageusia, but not anosmia, and raising questions about long-term effects like cognitive issues.

Chagas disease (American trypanosomiasis) is a 'neglected' pathology that affects millions of people worldwide, mainly in Latin America. , the causative agent, is an obligate intracellular parasite with a complex and diverse biology that infects several mammalian species, including humans. Because of genetic variability among strains and the presence of four biochemically and morphologically distinct parasite forms, the outcome of infection varies considerably depending on host cell type and parasite strain.
