Local TSH/TSHR signaling promotes CD8+ T cell exhaustion and immune evasion in colorectal carcinoma

Cancer Communications, Volume 44, Issue 11, Page 1287-1310, November 2024.
Abstract Background Dysfunction of CD8+ T cells in the tumor microenvironment (TME) contributes to tumor immune escape and immunotherapy tolerance. The effects of hormones such as leptin, steroid hormones, and glucocorticoids on T cell function have been reported previously.

Mechanism of Precipitin Reaction. II. Fractionation of Immunologically Pure Precipitin

Experimental Biology and Medicine, 1938
We have reported previously1 that the antibody of Type I Pneumococcus in horse or rabbit serum is separable into fractions with different immunological and physical properties and that the separation can be achieved by immunological or chemical methods.

All roads lead to IgA: Mapping the many pathways of IgA induction in the gut

Immunological Reviews, Volume 326, Issue 1, Page 66-82, September 2024.
Summary The increasing prevalence of food allergy and related pathologies in recent years has underscored the need to understand the factors affecting adverse reactions to food. Food allergy is caused when food‐specific IgE triggers the release of histamine from mast cells. However, other food‐specific antibody isotypes exist as well, including IgG and

Ecological patterns of blood-feeding by kissing-bugs (Hemiptera: Reduviidae: Triatominae)

Memorias do Instituto Oswaldo Cruz, 2011
Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect humans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of Chagas disease, is presented. For
