Chemokines in Alzheimer's Disease: Early Defence, Late Damage and the Impact of Sex and Infection

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 2, August 2026.
ABSTRACT Chemokines constitute a versatile signalling network maintaining homeostasis and glia–neuron communication in the healthy brain but become progressively dysregulated during aging and Alzheimer's disease (AD). This review examines how chemokine systems transition from tightly regulated homeostatic signals to drivers of chronic neuroinflammation

Antigenicity of cystatin-binding proteins from parasitic protozoan Detection by a proteinase inhibitor based capture immunoassay (PINC-ELISA) [PDF]

Journal of Immunological Methods, 1995
A novel immunoassay (PINC-ELISA) was designed using proteinase inhibitors of the cystatin superfamily (PINC) in the solid phase, to promote the selective capture of cysteine proteinases. The method was applied in the identification of papain-like antigens from parasitic protozoa. PINC of human origin, namely recombinant cystatin C (r-cystatin C) or low

From Infection to Anxiety: A Sequential Model Linking Latent Toxoplasmosis to Psychological Distress via Health and Stress

Scandinavian Journal of Psychology, Volume 67, Issue 4, Page 1026-1043, August 2026.
ABSTRACT Identifying the drivers of chronic stress is crucial for understanding its impact on mental health. Latent toxoplasmosis, a widespread parasitic infection, has been linked to various psychological changes. The Stress‐Coping Hypothesis proposes that at least some of these changes are consequences of chronic stress arising from the infection's ...

T‐cell responses to viral, bacterial and protozoan antigens in rheumatoid inflammation. Selective migration of T cells to synovial tissue [PDF]

Rheumatology, 2001
To identify any preferential or selective migration of T-cell specificities to inflamed tissues of rheumatoid arthritis (RA) patients.Lymphocytes from peripheral blood (PB) and synovial tissue (ST) were isolated from RA patients and stimulated with a panel of crude antigen preparations from 18 bacterial, protozoan and viral sources.
