Studies were initiated to determine if it was possible to use a tumor-bearing animal's own spleen cells to impart resistance to its neoplasm. YC8 T-cell lymphoma-bearing BALB/c mice (TBAs) were immunized with allogeneic DBA/2 spleen cells, which share cross-reacting antigens with the YC8 tumor. Animals immunized with the alloantigen were splenectomized and their spleen cells co-cultured with additional alloantigens for 2 days in media containing 2% polyethylene glycol (PEG) before being returned to the cyclophosphamide (cytoxan) (Ctx) pretreated autologous host. Treatment with Ctx was used to reduce suppressor factors in the TBA. It was found that when cultured spleen cells were returned to the autologous TBA, much greater resistance was imparted to the host and, in many instances, regression of the YC8 tumor was observed.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Background: T/histiocyte-rich large B-cell lymphoma (T/HRBCL) is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes. T/HRBCL commonly affects the lymph nodes, followed by extranodal sites, such as the spleen, liver, and bone marrow, with rare occurrences in the gastrointestinal tract. Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations, and it is difficult to differentiate from inflammatory diseases, nodular lymphocyte predominant Hodgkin lymphoma, and other diseases on a histological basis, thereby hindering early diagnosis.

Objective: To evaluate the effects of Fu Tu Sheng Jin Rehabilitation Formula (FTSJRF) on airway inflammation, mucus secretion, and immunoreaction in a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein-induced mouse model.
Methods: Forty-two mice were randomly divided into seven groups: normal, D1, D3, D10, D10H, D10M and D10L, according to the days of modeling and different dosages of FTSJRF. D1, D3, D10, D10H, D10M and D10L group mice were intratracheally administered with 15 µg SARS-CoV-2 spike protein; mice in the D10H, D10M, and D10L groups were intragastrically administered FTSJRF (46, 23 and 11.

Studying the human immune system in vivo is challenging and often not possible. Therefore, most human immunology studies have been predominantly confined to peripheral blood analyses, which by themselves have inherent limitations, as many immune reactions take place within tissues. For example, potent antibody responses that contribute to fighting infections and provide protection following vaccination require cellular interactions between B cells and T cells in specialized micro-anatomical structures called germinal centers, which are found in secondary lymphoid organs such as spleen, lymph nodes, and tonsils.

Brucella is a gram negative, facultative intracellular bacterial pathogen that constitutes a substantial threat to human and animal health. Brucella can replicate in a variety of tissues and can induce immune responses that alter host metabolite availability. Here, mice were infected with B.
