Immunity: Insect Immune Memory Goes Viral [PDF]

open access: yesCurrent Biology, 2017
Adaptive memory in insect immunity has been controversial. In this issue, Andino and co-workers propose that acquisition of viral sequences in the host genome gives rise to anti-sense, anti-viral piRNAs. Such sequences can be regarded as both a genomic archive of past infections and as an armour of potential heritable memory.

Natalizumab affects T-cell phenotype in multiple sclerosis: implications for JCV reactivation [PDF]

open access: yes, 2016
The anti-CD49d monoclonal antibody natalizumab is currently an effective therapy against the relapsing-remitting form of multiple sclerosis (RRMS). Natalizumab therapeutic efficacy is limited by the reactivation of the John Cunningham polyomavirus (JCV ...

Resident macrophages acquire innate immune memory in staphylococcal skin infection

open access: yeseLife, 2020
Staphylococcus aureus (S. aureus) is a common colonizer of healthy skin and mucous membranes. At the same time, S. aureus is the most frequent cause of skin and soft tissue infections.

Cross-Neutralization of Emerging SARS-CoV-2 Variants of Concern by Antibodies Targeting Distinct Epitopes on Spike

open access: yesmBio, 2021
Several severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants have arisen that exhibit increased viral transmissibility and partial evasion of immunity induced by natural infection and vaccination. To address the specific antibody targets

The roles of resident, central and effector memory CD4 T cells in protective immunity following infection or vaccination [PDF]

open access: yes, 2018
Immunological memory provides rapid protection to pathogens previously encountered through infection or vaccination. CD4 T cells play a central role in all adaptive immune responses.

CD4+ T-cell independent secondary immune responses to Pneumocystis pneumonia

open access: yesFrontiers in Immunology, 2016
Pneumocystis pneumonia is a major cause of morbidity and mortality among immunocompromised patients, especially in the context of HIV/AIDS. In the murine model of Pneumocystis pneumonia, CD4+ T-cells are required for clearance of a primary infection of ...

The Regulatory-T-Cell Memory Phenotype: What We Know

open access: yesCells, 2022
In immunology, the discovery of regulatory T (Treg) cells was a major breakthrough. Treg cells play a key role in pregnancy maintenance, in the prevention of autoimmune responses, and in the control of all immune responses, including responses to self ...

Protection against pertussis in humans correlates to elevated serum antibodies and memory B cells [PDF]

open access: yes, 2017
Pertussis is a respiratory infection caused by Bordetella pertussis that may be particularly severe and even lethal in the first months of life when infants are still too young to be vaccinated. Adults and adolescents experience mild symptoms and are the

Transmission immunity in malaria: reflections on the underlying immune mechanisms during natural infections and following artificial immunization

open access: yesMemorias do Instituto Oswaldo Cruz, 1992
Malaria transmission-blocking immunity has been studied in natural malaria infections in man, during infections in animals and following artificial immunization of animals with sexual stage malaria parasites.
