Mutational landscape of HSP family on human breast cancer.

Breast cancer (BRCA) is a prevalent malignancy with the highest incidence among females. BRCA can be categorized into five intrinsic molecular subtypes (LumA, LumB, HER2, Basal, and Normal), each characterized by varying molecular and clinical features determined by the expression of intrinsic genes (PAM50). The Heat Shock Protein (HSP) family is composed of 95 genes evolutionary conservated, they have critical roles in proteostasis in both normal and cancerous processes.

Antiparasitic Activity of Two Natural Terpenes from against .

Leishmaniasis is a neglected disease caused by flagellated parasites of the genus affecting more than 10 million people worldwide. Current treatments for leishmaniasis involve the administration of poorly tolerated drugs with toxic side effects in patients. There is an imperative necessity for novel compounds to treat this disease.

Receptor-binding domain-based SARS-CoV-2 vaccine adjuvanted with cyclic di-adenosine monophosphate enhances humoral and cellular immunity in mice.

Novel adjuvants are highly desired to improve immune responses of SARS-CoV-2 vaccines. This work reports the potential of the stimulator of interferon genes (STING) agonist adjuvant, the cyclic di-adenosine monophosphate (c-di-AMP), in a SARS-CoV-2 vaccine based on the receptor binding domain (RBD). Here, mice immunized with two doses of monomeric RBD adjuvanted with c-di-AMP intramuscularly were found to exhibit stronger immune responses compared to mice vaccinated with RBD adjuvanted with aluminum hydroxide (Al(OH) ) or without adjuvant.

Placental leukocyte infiltration accompanies gestational changes induced by hyperthyroidism.

In Brief: The endocrine and immunological disruption induced by hyperthyroidism could alter gestation, placenta, and fetal development. This study suggests an immunological role of thyroid hormones in gestation.

Abstract: Thyroid dysfunctions lead to metabolic, angiogenic, and developmental alterations at the maternal-fetal interface that cause reproductive complications.

Identification of Immunodominant Antigens From a First-Generation Vaccine Against Cutaneous Leishmaniasis.

Leishmaniasis is a neglected tropical disease (NTD) caused by parasites belonging to the genus for which there is no vaccine available for human use. Thus, the aims of this study are to evaluate the immunoprotective effect of a first-generation vaccine against and to identify its immunodominant antigens. BALB/c mice were inoculated with phosphate buffer sodium (PBS), total antigens (TLAs), or TLA with Poly (I:C) and Montanide ISA 763.

Therapeutic effect of (LAM) BENTH aqueous extract on a murine model of cutaneous leishmaniasis.

Background And Aim: (Lam.) Benth is a rhizomatous shrub native from different zones of Argentine Republic. aqueous extract (PsAE) has different effects and several biological activities have been reported.

Desmoglein-4 Deficiency Exacerbates Psoriasiform Dermatitis in Rats While Psoriasis Patients Displayed a Decreased Gene Expression of DSG4.

Desmogleins are involved in cell adhesion conferring structural skin integrity. However, their role in inflammation has been barely studied, and whether desmoglein-4 modulates psoriasis lesions is completely unknown. In this study, we assessed the impact of desmoglein-4 deficiency on the severity of imiquimod (IMQ)-induced skin inflammation and psoriasiform lesions.

Leishmania (L.) amazonensis infection impairs reproductive and fetal parameters in female mice.

Leishmaniasis is a group of parasitic zoonotic diseases caused by intracellular protozoans belonging to the genus Leishmania. Little is known about the effects that this parasitosis may have on the reproductive parameters and pregnancy of infected humans and pets. This study aimed to evaluate the influence of chronic cutaneous leishmaniasis caused by Leishmania (Leishmania) amazonensis on reproductive and fetal parameters using a female murine model.

Evaluation of different total Leishmania amazonensis antigens for the development of a first-generation vaccine formulated with a Toll-like receptor-3 agonist to prevent cutaneous leishmaniasis.

BACKGROUND Unfortunately, no any vaccine against leishmaniasis has been developed for human use. Therefore, a vaccine based on total Leishmania antigens could be a good and economic approach; and there are different methodologies to obtain these antigens. However, it is unknown whether the method to obtain the antigens affects the integrity and immune response caused by them.

A Mouse Model of Diet-Induced Obesity Resembling Most Features of Human Metabolic Syndrome.

Increased chicken-derived fat and fructose consumption in the human diet is paralleled by an increasing prevalence of obesity and metabolic syndrome (MS). Herein, we aimed at developing and characterizing a mouse model of diet-induced obesity (DIO) resembling most of the key features of the human MS. To accomplish this, we fed male C57BL/6J mice for 4, 8, 12, and 16 weeks with either a low-fat diet (LFD) or a high-chicken-fat diet (HFD) and tap water with or without 10% fructose (F).
