Toxin-neutralizing antibodies protect against Clostridium perfringens-induced necrosis in an intestinal loop model for bovine necrohemorrhagic enteritis [PDF]

open access: yes, 2016
Background: Bovine necrohemorrhagic enteritis is caused by Clostridium perfringens type A. Due to the rapid progress and fatal outcome of the disease, vaccination would be of high value. In this study, C.

Genetic Modification of Limbal Stem Cells to Decrease Allogeneic Immune Responses

open access: yesFrontiers in Immunology, 2021
Limbal stem cell (LSC) transplantation is the only efficient treatment for patients affected by LSC deficiency (LSCD). Allogeneic LSC transplantation is one of the most successful alternative for patients with bilateral LSCD.

Cytotoxic Isoantibodies and Immunologic Enhancement in Mice.

open access: yesExperimental Biology and Medicine, 1966
Summary1. Cytotoxic isoantibodies and hemagglutinins are stimulated in response to H-2 isoantigenic differences between graft and host in mice. 2. This study offers data correlating cytotoxic isoantibody and immunological enhancement. 3. The mechanism of immunological enhancement has been shown to be associated with peripheral as well as central ...

In vitro Cytotoxicity in Delayed-Type Hypersensitivity and Immunologic Tolerance.

open access: yesExperimental Biology and Medicine, 1964
SummaryPicryl chloride was found to exert a lethal effect in vitro on leukocytes, principally lymphocytes, from guinea pigs exhibiting delayed-type skin reactivity to this hapten in the absence of antibody and complement. This reaction was found to be immunologically specific.

NKp46 clusters at the immune synapse and regulates NK cell polarization

open access: yesFrontiers in Immunology, 2015
Natural killer cells play an important role in first-line defense against tumor and virus-infected cells. The activity of NK cells is tightly regulated by a repertoire of cell-surface expressed inhibitory and activating receptors.

Negative Regulation and Protective Function of Natural Killer Cells in HIV Infection: Two Sides of a Coin

open access: yesFrontiers in Immunology, 2022
Natural killer (NK) cells play an important immunologic role, targeting tumors and virus-infected cells; however, NK cells do not impede the progression of human immunodeficiency virus (HIV) infection.
