Adaptive Immune-Response to Tick-Borne Hemoparasites
Interactions between tick-borne pathogenic hemoparasites and different host effector mechanisms of T- and/or B cell-mediated adaptive immunity, involved in the late and long-lasting protective immune response.

Adaptive Immunity and Diabetic Retinopathy
Diabetic retinopathy (DR) is currently one of the common causes of vision loss in working-age adults. It is clinically diagnosed and classified according to the vascular changes in the fundus. The activation of immune cells occurs before these vascular changes become detectable. These, together with molecular studies and the positive clinical outcomes of anti-inflammatory treatment, highlight the pivotal involvement of the immune system. The role of innate immunity in DR pathophysiology has been studied in depth, but the contribution of adaptive immunity remains largely elusive.

Adaptive Immunity in Older People
Vaccination is the best strategy to prevent this fact, but older people present a less efficient response, as their immune system is weaker due mainly to a phenomenon known as immunosenescence. The adaptive immune system is constituted by two types of lymphocytes, T and B cells, and the function and fitness of these cell populations are affected during ageing.

Adaptive Natural Killer Cells
Natural killer (NK) cells play a significant and vital role in the first line of defense against infection through their ability to target cells without prior sensitization. They also contribute significantly to the activation and recruitment of both innate and adaptive immune cells through the production of a range of cytokines and chemokines. In the context of cytomegalovirus (CMV) infection, NK cells and CMV have co-evolved side by side to employ several mechanisms to evade one another. However, during this co-evolution the discovery of a subset of long-lived NK cells with enhanced effector potential, increased antibody-dependent responses and the potential to mediate immune memory has revolutionized the field of NK cell biology. The ability of a virus to imprint on the NK cell receptor repertoire resulting in the expansion of diverse, highly functional NK cells to this day remains a significant immunological phenomenon that only occurs in the context of CMV.

Adipokines
Adipokines are adipose tissue-derived factors not only playing an important role in metabolism but also influencing other central processes of the body, such as inflammation.

Adoptive Immunotherapy beyond CAR T-Cells
The aging of the world population leads to a constant increase of cancer-related morbidity and mortality. Treatment of late-stage tumors has become a significant burden on the healthcare system globally. Adoptive cell immunotherapy is supposed to prolong life with cancer and ideally cure cancer after a single infusion of the cell product. Arguably, the most impressive clinical therapy in this field is based on chimeric antigen receptor (CAR) T-cells capable of curing up to 25–50% of previously incurable patients with B-cell malignancies. Diverse cell therapies are already efficiently used in clinics for cancer treatment (such as tumor infiltrating lymphocytes, transgenic αβ T-cells) and several novel promising cell therapies are in development (such as CAR M-cells, transgenic γδ T-cells, CAR NK-cells). Here, we summarize the recent literature data with the focus on T-cell receptor-based therapies and overview the most advanced systems for manufacturing of clinical grade cell products.

Advances in Immunotherapy for Hepatitis B
Hepatitis B virus (HBV) is a hepatotropic virus with the potential to cause chronic infection, and it is one of the common causes of liver disease worldwide. Chronic HBV infection leads to liver cirrhosis and, ultimately, hepatocellular carcinoma (HCC). Progress in Hepatitis-B-Specific Immunotherapy is discussed.

Alarmins and MicroRNAs in Genesis of Respiratory Diseases
Alarmins support the pathogenesis of chronic respiratory diseases as asthma through ferroptosis and the axis composed of high mobility group box 1 (HMGB1) and interleukin (IL)-33. The mechanisms supporting the development and progression of chronic respiratory diseases and the role of HMBG1 and IL-33 are described.

Alcohol-Induced Liver Injury in Brief
Alcoholic liver disease (ALD) is a global health concern, representing a spectrum of liver disorders resulting from chronic alcohol consumption. To decipher the intricate mechanisms underlying ALD and develop effective therapies, researchers have turned to experimental models. Among these, the alcohol-induced liver injury model, accomplished through chronic alcohol administration to animals, has been pivotal in elucidating key pathophysiological aspects of ALD. This research navigates through the methodologies employed to induce liver injury, highlights the diverse pathological features observed, explores the underlying mechanisms, and discusses the model's relevance in advancing our understanding of ALD. Additionally, it delves into the multifaceted applications of this model in the quest for novel therapeutic strategies to combat ALD.

Allergenic and Anti-Allergenic Antibodies in Food Allergy
Food allergies are a growing public health concern worldwide, especially in children and young adults. Allergen-specific IgE plays a central role in the pathogenesis of food allergies, but their titers poorly correlate with allergy development. Host immune systems yield allergen-specific immunoglobulin (Ig)A, IgE and IgG subclasses with low or high affinities and differential Fc N-glycosylation patterns that can affect the allergic reaction to food in multiple ways. High-affinity IgE is required to induce strong mast cell activation eventually leading to allergic anaphylaxis, while low-affinity IgE can even inhibit the development of clinically relevant allergic symptoms. IgA and IgG antibodies can inhibit IgE-mediated mast cell activation through various mechanisms, thereby protecting IgE-positive individuals from allergy development. The production of IgE and IgG with differential allergenic potential seems to be affected by the signaling strength of individual B cell receptors, and by cytokines from T cells.
