Long-Term SARS-CoV-2-Specific Humoral and T Cell Responses after the BNT162b2 or BBIBP-CorV Booster and the Incidence of Breakthrough Infections among Healthcare Workers.

The effectiveness of COVID-19 vaccines developed against the original virus strain deteriorated noticeably in efficacy against the Omicron variant (B.1.1.

Diagnosis of neuroborreliosis in the context of local seroprevalence: A chart review study and a methodological overview.

Background & Objectives: In neuroborreliosis (NB) serology might objectively differentiate ongoing from past infection when the intrathecal space is involved. The hierarchy of the parallel serum-CSF (cerebrospinal fluid) methods is seldom discussed and remains elusive in daily practice. We compared the efficacy of certain methods and assessed the prevalence of anti-Borrelia antibodies in the local population.

Chemogenetic approaches reveal dual functions of microglia in seizures.

Microglia are key players in maintaining brain homeostasis and exhibit phenotypic alterations in response to epileptic stimuli. However, it is still relatively unknown if these alterations are pro- or anti-epileptic. To unravel this dilemma, we employed chemogenetic manipulation of microglia using the artificial Gi-Dreadd receptor within a kainic acid (KA) induced murine seizure model.
